APPLICATIONS
1. GENERAL DESCRIPTION
Included in the IC are; Four Switching Buck controllers for 5V and 3.3V system voltages as well as VDDQ and 1.05V, Six LDOs for variety of applications such as memory VTT and Vpp, One internal high frequency 3A Buck regulator typically used for 1.8V supply and One Dual Input Single output switch. The PWM controllers use the ANPEC cost effective external Power Blocks APW870x family for minimum pin interface with the PMIC, while providing output currents of up to 25A capability. The IC is equipped with all the standard protection features such as over current, over voltage and internal under voltage lock out protection as well as thermal SD. The serial interface is an I2C communication interface which allows supply sequencing as well as controlled margining of ramp up and ramp down of all supplies to optimize battery power consumption. The I2C interface also allows for adjustability of Soft Start, Forced PWM/Auto PFM/PWM, power sequencing as well output discharge and IRQ.
