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 furt...
