FAN4860 - 5V Output Synchronous TinyBoost Regulator

General Description

The FAN4860 is a low-power boost regulator designed to provide a regulated 5V output from a single cell Li-Ion battery.

The output voltage is fixed at 5.0V with a guaranteed maximum load current of 200mA at VIN=2.3V and 300mA at VIN=3.3V.

Key Features

  • Operates with Very Small External Components: 1μH Inductor and 0402 Case Size Input and Output Capacitors.
  • Input Voltage Range from 2.3V to 4.5V.
  • Fixed 5.0V Output Voltage.
  • Maximum Load Current 200mA at VIN=2.3V.
  • Maximum Load Current 300mA at VIN=3.3V.
  • Up to 92% Efficient.
  • Low Operating Quiescent Current.
  • True Load Disconnect During Shutdown.
  • Variable On-time Pulse Frequency Modulation (PFM) with Light-Load Power-Saving Mode.
  • Internal Synchronou.
