These modules operate over a wide range of input voltage (V = 3Vdc-14.4Vdc) and provide a precisely regulated output IN voltage from 0.45Vdc to 5.5Vdc, programmable via an external resistor and PMBus control. Features include a digital interface using the PMBus protocol, remote On/Off, adjustable output voltage, over current and over temperature protection. The PMBus TM interface supports a range of commands to both control and monitor the module. The module also includes the Tunable Loop feature that allows the user to optimize the dynamic response of the converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area. * UL is a registered trademark of Underwriters Laboratories, Inc. † CSA is a registered trademark of Canadian Standards Association. ‡ VDE is a trademark of Verband Deutscher Elektrotechniker e.V. ** ISO is a registered trademark of the International Organization of Standards # The PMBus name and logo are registered trademarks of the System Management Interface Forum (SMIF) November 4, 2016 ©2016 General Electric Company.

A highly inductive source can affect the stability of the module. An input capacitance must be placed directly 40 adjacent to the input pin of the module, to minimize input ripple voltage and ensure module stability. To minimize input voltage ripple, ceramic capacitors are recommended at the input of the module. Figure 37 shows 20 the input ripple voltage for various output voltages at 12A of load current with 1x22 µF or 2x22 µF ceramic capacitors and an input of 12V. 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 450 1x22uF 400 Output Voltage(Volts) 2x22 uF 350 Figure 38.

Input voltage is 12V. 20MHz BW For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV), the input Output Filtering must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. These modules are designed for low output ripple voltage and will meet the maximum output ripple specification with The input to these units is to be provided with a fast-acting 3x0.047 µF ceramic and 2x47 µF ceramic capacitors at the fuse (e.g. ABC Bussmann) with a maximum rating of 20 A in output of the module. However, additional output filtering the positive input lead. may be required by the system designer for a number of reasons. First, there may be a need to further reduce the output ripple and noise of the module. Second, the dynamic response characteristics may need to be customized to a particular load step change. To reduce the output ripple and improve the dynamic response to a step load change, additional capacitance at the output can be used. Low ESR polymer and ceramic capacitors are recommended to improve the dynamic response of the module. Figure 38 provides output ripple information, measured with a scope with its Bandwidth limited to 20MHz for different external capacitance values at various Vo and a full load current of 12A. For stable operation of the module, limit the capacitance to less than the maximum output capacitance as specified in the electrical specification table. Optimal performance of the TM module can be achieved by using the Tunable Loop feature described later in this data sheet. November 4, 2016 ©2016 General Electric Company. All rights reserved.

The module can be configured in a number of ways through the PMBus interface to react to the two ON/OFF I ON/OFF inputs: ENABLE +  Module ON/OFF can be controlled only through Q1 the analog interface (digital interface ON/OFF V commands are ignored) ON/OFF  Module ON/OFF can be controlled only through the PMBus interface (analog interface is ignored) _ GND  Module ON/OFF can be controlled by either the analog or digital interface The default state of the module (as shipped from the factory) Figure 39. Circuit configuration for using positive On/Off is to be controlled by the analog interface only. If the digital logic. interface is to be enabled, or the module is to be controlled only through the digital interface, this change must be made SLIMLYNX MODULE through the PMBus.

Rpullup Analog On/Off 10K TM The 12A Digital Pico SlimLynx Open Frame power modules ENABLE I ON/OFF feature an On/Off pin for remote On/Off operation. Two 22K Q2 On/Off logic options are available. In the Positive Logic + On/Off option, (device code suffix “4” – see Ordering Q1 Information), the module turns ON during a logic High on the V 22K ON/OFF On/Off pin and turns OFF during a logic Low. With the Negative Logic On/Off option, (no device code suffix, see Ordering Information), the module turns OFF during logic _ GND High and ON during logic Low. The On/Off signal should be always referenced to ground. For either On/Off logic option, Figure 40.

By connecting multiple modules together, multiple modules can track their output voltages to the voltage applied on the SEQ pin. The module’s output can track the SEQ pin signal with slopes of up to 0.5V/msec during power-up or power-down. To initiate simultaneous shutdown of the modules, the SEQ pin voltage is lowered in a controlled manner. The output voltage of the modules tracks the voltages below their set- point voltages on a one-to-one basis. A valid input voltage must be maintained until the tracking and output voltages reach ground potential.

If the converter is sinking threshold is set higher than the POWER_GOOD_OFF current a reading of 0 is provided. The READ_IOUT threshold. command returns two bytes of data in the linear data format. The exponent uses the upper five bits [7:3] of the Both POWER_GOOD_ON and POWER_GOOD_OFF high data byte in two-s complement format and is fixed at – commands use the “Linear” format with the exponent fixed 4 (decimal). The remaining 11 bits in two’s complement at –10 (decimal).

Failure to to Board Mounted Power Modules: Soldering and Cleaning observe the instructions below may result in the failure of or Application Note (AN04-001). cause damage to the modules and can adversely affect long-term reliability. Pb-free Reflow Profile Power Systems will comply with J-STD-020 Rev. D (Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices) for both Pb-free solder profiles and MSL classification procedures. This standard provides a recommended forced-air-convection reflow profile based on the volume and thickness of the package (table 4-2). The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The recommended linear reflow profile using Sn/Ag/Cu solder is shown in Fig. 50. Soldering outside of the recommended profile requires testing to verify results and performance. MSL Rating TM The 12A Digital Pico SlimLynx Open Frame modules have a MSL rating of 2a. Storage and Handling The recommended storage environment and handling procedures for moisture-sensitive surface mount packages is detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices). Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 2 or greater. These sealed packages should not be broken until time of use. Once the original package is broken, the floor life of the product at conditions of  30°C and 60% relative humidity varies according to the MSL rating (see J-STD-033A). The shelf life for dry packed SMT packages will be a minimum of 12 months from the bag seal date, November 4, 2016 ©2016 General Electric Company. All rights reserved.
