ST1PS02

Description

The ST1PS02 is a nano-quiescent miniaturized synchronous step-down converter, which is able to provide up to 400 mA output current with an input voltage ranging from 1.8 V to 5.5 V.

Key Features

  • 500 nA input quiescent current at VIN = 3.6 V (not switching)
  • 92% typical efficiency at 10 mA load (VIN = 3.6 V, VOUT = 2.5 V)
  • 100% duty cycle
  • 1.8 V to 5.5 V input operating range
  • Undervoltage lockout: 1.57 V (VIN falling, typ.)
  • Up to 400 mA output current capability
  • Low power control operation for the best efficiency
  • Embedded soft-start circuit
  • Settable inductor current limitation
  • Selectable output voltages: 1.0 V to 3.3 V
