Product Overview

The ST1S40IPUR is a DC step-down Switching Regulator with cycle-by-cycle current limiting. This device is an internally compensated 850kHz fixed-frequency PWM synchronous step-down regulator. This integrates a 95mR high side switch and 69mR synchronous rectifier allowing very high efficiency with very low output voltages. The peak current mode control with internal compensation delivers a very compact solution with a minimum component count.
  • Internal soft-start
  • All ceramic capacitor
  • Current fold back short-circuit protection
