ISL9305H
3MHz Dual 1.5A Step-Down Converters and Dual Low-Input LDOs with I2C Compatible Interface
FN7724 Rev 2.00 March 7, 2014
The ISL9305H is an integrated mini Power Management IC (mini-PMIC) for powering low-voltage microprocessors, or applications using a single Li-Ion or Li-Polymer cell battery to power multiple voltage rails. The ISL9305H 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.
