These modules operate over a wide range of input voltage (VIN = 2.4Vdc-5.5Vdc) and provide a precisely regulated output voltage from 0.6Vdc to 3.63Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over current and overtemperature protection, and output voltage sequencing (APTH versions). A new TM feature, the Tunable Loop , 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 September 11, 2013 ©2013 General Electric Company.

Output Voltage Programming TM The output voltage of the Micro TLynx module can be programmed to any voltage from 0.6dc to 3.63Vdc by connecting a resistor between the Trim+ and GND pins of the module. Certain restrictions apply on the output voltage set point depending on the input voltage. These are shown in the Output Voltage vs. Input Voltage Set Point Area plot in Fig. 40. The Upper Limit curve shows that the entire output voltage range is available with the maximum input voltage of 5.5V.

GND Vo Figure 41. Circuit configuration for programming output Rmargin-down voltage using an external resistor. MODULE Remote Sense Q2 TM The Micro TLynx modules have a Remote Sense feature to minimize the effects of distribution losses by regulating the Trim voltage at the SENSE pin. The voltage between the SENSE pin Rmargin-up and VOUT pin must not exceed 0.5V. Note that the output voltage of the module cannot exceed the specified maximum Rtrim value. This includes the voltage drop between the SENSE and Vout pins. When the Remote Sense feature is not being used, Q1 connect the SENSE pin to the VOUT pin. GND Figure 42. Circuit Configuration for margining Output voltage Monotonic Start-up and Shutdown TM The Micro TLynx modules have monotonic start-up and shutdown behavior for any combination of rated input voltage, output current and operating temperature range. Startup into Pre-biased Output TM The 5.5V Pico TLynx 12A modules can start into a prebiased output as long as the prebias voltage is 0.5V less than the set output voltage. Note that prebias operation is not supported when output voltage sequencing is used. Output Voltage Sequencing The APTH012A0X modules include a sequencing feature, EZ- SEQUENCE that enables users to implement various types of output voltage sequencing in their applications. This is accomplished via an additional sequencing pin. When not using the sequencing feature, either tie the SEQ pin to VIN or leave it unconnected. When an analog voltage is applied to the SEQ pin, the output voltage tracks this voltage until the output reaches the set-point voltage. The final value of the SEQ voltage must be set higher than the set-point voltage of the module. The output voltage follows the voltage on the SEQ pin on a one-to-one volt basis. By connecting multiple modules together, multiple modules can track their output voltages to the voltage applied on the SEQ pin. September 11, 2013 ©2013 General Electric Company.

The On/Off pin of the module is left unconnected Lineage Power technical representative for additional (or tied to GND for negative logic modules or tied to VIN for information. positive logic modules) so that the module is ON by default. After applying input voltage to the module, a minimum 10msec delay is required before applying voltage on the SEQ pin. This delay gives the module enough time to complete its internal power-up soft-start cycle. During the delay time, the SEQ pin should be held close to ground (nominally 50mV ± 20 mV). This is required to keep the internal op-amp out of saturation thus preventing output overshoot during the start of the sequencing ramp. By selecting resistor R1 (see fig. 43) according to the following equation 24950 R1 = ohms, V − 0.05 IN the voltage at the sequencing pin will be 50mV when the sequencing signal is at zero. MODULE VIN+ 499K + OUT R1 - SEQ 10K GND Figure 43. Circuit showing connection of the sequencing signal to the SEQ pin. After the 10msec delay, an analog voltage is applied to the SEQ pin and the output voltage of the module will track this voltage on a one-to-one volt bases until the output reaches the set- point voltage. 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. TM When using the EZ-SEQUENCE feature to control start-up of the module, pre-bias immunity during start-up is disabled. The pre-bias immunity feature of the module relies on the module being in the diode-mode during start-up. When using the EZ- TM SEQUENCE feature, modules goes through an internal set-up time of 10msec, and will be in synchronous rectification mode when the voltage at the SEQ pin is applied. This will result in the module sinking current if a pre-bias voltage is present at the output of the module. When pre-bias immunity during TM start-up is required, the EZ-SEQUENCE feature must be disabled. For additional guidelines on using the EZ- TM SEQUENCE feature please refer to Application Note AN04- 008 “Application Guidelines for Non-Isolated Converters: September 11, 2013 ©2013 General Electric Company.
