ISL9307
3MHz Dual 1500mA Step-Down Converters and Dual Low-Input LDOs
FN7931 Rev 3.
00 September 20, 2012
The ISL9307 is an integrated mini Power Management IC (mini-PMIC) ideal for applications for powering low-voltage microprocessor or multiple voltage rails with a battery as an input source, such as a single Li-ion or Li-polymer.
ISL9307 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 ef...
