Overview

DATASHEET ISL9305 3MHz Dual Step-Down Converters and Dual Low-Input LDOs with I2C Compatible Interface FN7605 Rev 2.00 February 9, 2015 The ISL9305 is an integrated mini Power Management IC (mini-PMIC) ideal for applications of powering low-voltage microprocessor or multiple voltage rails with battery as input sources, such as a single Li-ion or Li-Polymer.

ISL9305 integrates two high-efficiency 3MHz synchronous step-down converters (DCD1 and DCD2) and two low-input, low-dropout linear regulators (LDO1 and LDO2).

The 3MHz PWM switching frequency allows the use of very small external inductors and capacitors.
