Overview

DATASHEET ISL91110IR High Efficiency Buck-Boost Regulator with 5.4A Switches FN8709 Rev 0.00 April 17, 2015 The ISL91110IR is a high-current buck-boost switching regulator for systems using new battery chemistries.

It uses Intersil’s proprietary buck-boost algorithm to maintain voltage regulation while providing excellent efficiency and very low output voltage ripple when the input voltage is close to the output voltage.

The ISL91110IR is capable of delivering at least 2A continuous output current (VOUT = 3.3V) over a battery voltage range of 2.5V to 4.35V.

Key Features

Accepts input voltages above or below regulated output voltage.
Automatic and seamless transitions between buck and boost modes.
Input voltage range: 1.8V to 5.5V.
Output current: up to 2A (PVIN = 3.4V, VOUT = 5V).
Output current: up to 2A (PVIN = 2.5V, VOUT = 3.3V).
Burst current: up to 3A (PVIN = 2.9V, VOUT = 3.3V, tON < 600µs, t = 4.6ms).
High efficiency: up to 95%.
35µA quiescent current maximizes light load efficiency.
