GENERAL DESCRIPTION

The ACT88760 PMIC is an integrated ActiveCiPSTM power management integrated circuit. It powers a wide range of processors, including, video processors, FPGA’s, wearables, peripherals, and microcontrollers. The ACT88760 is highly flexible and can be reconfig-ured via I2C for multiple applications without the need for PCB changes. The low external component count and high configurability significantly speeds time to mar-ket. Examples of configurable options include output voltage, startup time, slew rate, system level sequenc-ing, switching frequency, sleep modes, operating modes etc. ACT88760 is programmed at the factory with a default configuration. These settings can be opti-mized for a specific design through the I2C interface. The ACT88760 is available in several default configura-tion. Contact the factory for specific default configura-tions.

The ACT88760 integrates seven high efficiency switch-ing regulators, six linear regulators, and eleven GPIOs. Two LDOs can be configured as load switches. The eleven GPIOs pins are configurable and used for a va-riety of system functions.

The ACT88760 is designed to work with a single lithium ion or lithium polymer batteries with an input voltage up to 5.5V. It works with input voltages as low as 2.6V.

The seven switching converters are peak current mode, fixed frequency DC-DC step down converters. Buck1/2 and Buck3/4 can be paralleled for 8A or 6A of output current. The high switching frequencies allow small in-ductors which reduce solution size and optimize load transient response. The converters are internally com-pensated for small ceramic output capacitors.

Two LDOs are high PSRR with > 70dB. The other for are general purpose LDOs. LDO5/6 can be configured as load switches with less than 25mΩ RDSON.

The ACT88760 PMIC is available in a 3.85mm x 3.85mm 81 ball WLCSP package.
