General Description
The APW7704 is a Power Management IC (PMIC) designed to provide complete Power Management solution for the driving video recorder (DVR) applications. For the application, if the input power source supplies to VBUS term inal, the SLEEP pin short to ground is recommanded. Also, if the input source power supplies to the VSYS Terminal, It’s recommended the SLEEP and VSYS Pinouts terminal are connected togather and the VBUS pin shorts to grond.The APW7704 is designed to provide maximum number of regulators in the smallest available cost effective package. Included in the IC are: Four Synchronous Buck Converters for DC1 ~ DC4; Three LDOs with one for RTC application, and Two Load Switch Enable Signal Control for external load switches application. For the Bucks, the IC is equipped with all the standard protection features such as current limit, over voltage and internal under voltage lock out protection as well as thermal shutdown. The serial interface is an I²C communication interface. The I²C interface also allows for adjustability of VRs’voltage. Also, the power sequenc is defined by strobes and delay times under I²C Control. The device is available in a 40-pin, 5x5 mm² thin QFN package for best thermal performance while optimizing the cost.
