PMP8372: ±5V @ 1A, 7 ~ 40V in

Summary

The PMP8372 design is optimized for small size and uses the TPS84250 step-down power module on the top- side with the TPS84259 negative output power module on the bottom-side to implement both positive and negative output voltages from a 12V/24V source. The output voltages can be adjusted from +/-3V to +/-15V with resistor changes.

The design is capable of 1-A outputs. The positive-input TPS7A4700 LDO and negative-input TPS7A3301 LDO are included for a low noise, high PSRR solution that is ideal for powering bipolar amplifiers, data converters, or other noise-sensitive analog circuitry.
