FAN5308 - 800mA High-Efficiency Step-Down DC-DC Converter

General Description

Designed for use in battery-powered applications, the FAN5308 is a high-efficiency, low-noise synchronous PWM current mode and pulse skip (power-save) mode DC-DC converter.

It can provide up to 800mA of output current over an input range from 2.5V to 5.5V.

Key Features

  • 96% efficiency, synchronous operation.
  • Adjustable output voltage options from 0.8V to VIN.
  • 2.5V to 5.5V input voltage range.
  • Up to 800mA output current.
  • Fixed-frequency 1.3MHz PWM operation.
  • High-efficiency, power-save mode.
  • 100% duty cycle low-dropout operation.
  • Soft-start.
  • Output over-voltage protection.
  • Dynamic output voltage positioning.
  • 25µA quiescent current.
  • Thermal shutdown and short-circuit protection.
  • Pb-free 3x3mm 6-lea.
