Overview

The ISL9307IRTWCNJZ-T is an integrated mini Power Management IC (mini-PMIC) ideal for applications for poweringlow-voltage microprocessor or multiple voltage rails with a battery as an input source, such as a single Li-ion or Li-polymer. ISL9307IRTWCNJZ-T 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. Bothstep-down converters can enter skip mode under light load conditions to further improve efficiency and maximize battery life.The ISL9307IRTWCNJZ-T features EN pins for each channel, thus allowing startup delay for power sequencing.The ISL9307IRTWCNJZ-T also provides two 300mA low-dropout (LDO) regulators. The input voltage range is 1.5V to 5.5V, which allows them to be powered from one of the on-chip step-down converters or directly from a battery. The default LDO power-up output comes with factory pre-set fixed output voltage options between 0.9V and 3.3V.The ISL9307IRTWCNJZ-T is available in a 4mmx4mm 16 Ld TQFN.
