These modules operate over a wide range of input voltage (VIN = 4.5Vdc-13.8Vdc) and provide a precisely regulated output voltage from 0.59Vdc to 6Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over current and over temperature protection. A new feature, the Tunable LoopTM, allows the user to optimize the dynamic response of the converter to match the load. * UL is a registered trademark of Underwriters Laboratories, Inc. † ‡ CSA is a registered trademark of Canadian Standards Association.

A highly inductive source can affect the stability of the module. An input capacitance must be placed directly adjacent to the input pin of the module, to minimize input ripple voltage and ensure module stability. To minimize input voltage ripple, low-ESR ceramic or polymer capacitors are recommended at the input of the module. Figure 46 shows the input ripple voltage for various output voltages at 20A of load current with 2x22 µF or 4x22 µF ceramic capacitors and an input of 12V. 90 BATTERY CS 1000μF Electrolytic E.S.R.
