These modules operate over a wide range of input voltage (VIN = 3Vdc-14.4Vdc) and provide a precisely regulated output voltage from 0.6Vdc to 5.5Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over TM current and over temperature protection. 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 September 7, 2017 ©2017 General Electric Company.

A highly 40 inductive source can affect the stability of the module. An input capacitance must be placed directly adjacent to the 30 input pin of the module, to minimize input ripple voltage and ensure module stability. 20 To minimize input voltage ripple, ceramic capacitors are 10 recommended at the input of the module. Figure 37 shows the input ripple voltage for various output voltages at 20A 0 of load current with 2x22 µF or 3x22 µF ceramic capacitors 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 and an input of 12V.

The UVT040A0X series were tested using an external Output Filtering Littelfuse 456 series fast-acting fuse rated at 30 A, 100 Vdc These modules are designed for low output ripple voltage in the ungrounded input. and will meet the maximum output ripple specification with 0.1 µF ceramic and 2x47 µF ceramic capacitors at the output of the module. However, additional output filtering 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 for different external capacitance values at various Vo and a full load current of 20A. 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. September 7, 2017 ©2017 General Electric Company. All rights reserved.
