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.
Both step-down converters can enter skip mode under light load conditions to further improve the efficiency and maximize the battery life.
For noise sensitive applications, they can also be programmed through I2C interface to operate in forced PWM mode regardless of the load current condition.
The I2C interface supports on-the-fly slew rate control of the output voltage from 0.
