SP7656 Datasheet 29v Non-synchronous Buck Converter

Manufacturer: Exar (now MaxLinear)

Overview: SP7656 PowerBlox High-Voltage, Step-Down Converter in SO8-EP.

General Description

The SP7656 is a PWM controlled step down (buck) voltage mode regulator co-packaged with a PChannel FET.

It operates from 4.5V to 29V making it suitable for 5V, 12V and 24V applications.

The programmable overcurrent protection is based on internal FET’s ON resistance sensing and allows setting the overcurrent protection value up to 300mV threshold (measured between VIN-LX).
