Overview

DATASHEET ISL91117 High Efficiency Synchronous Boost Converter with 4.2A Switches and Output Disconnect FN8569 Rev 3.00 March 7, 2014 The ISL91117 is a highly-integrated boost switching regulator for battery powered applications.

The device provides a power supply solution for products using dual-cell or three-cell alkaline, NiCd or NiMH, or one-cell Li-ion or Li-polymer battery.

This device is capable of delivering an output current of 1.5A with PVIN = 3.3V and VOUT = 5V.

Key Features

  • Input voltage range: 1.8V to 4.8V.
  • Fixed 5V or adjustable output.
  • Output current: up to 1.5A (PVIN = 3.3V, VOUT = 5V).
  • High efficiency: up to 96%.
  • 35µA quiescent current maximizes light-load efficiency.
  • True input-output disconnect when disabled.
  • 2.6MHz switching frequency minimizes external component size.
  • Selectable forced-PWM mode and external synchronization.
  • Fully protected for short-circuit, over-temperature.
