ISL9307 - 3MHz Dual 1500mA Step-Down Converters and Dual Low-Input LDOs

Features

  • EN pins for each channel, thus allowing startup delay for power sequencing. The ISL9307 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.

DATASHEET 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 efficiency and maximize battery life.
