Power Management IC, Dual Synchronous 1.5A/1.5A Step-down Buck Regulators with 525 mA LDO

PM823 is a companion IC for NXP Wi-Fi and Bluetooth combo solutions 88W8977, 88W8987, 88W8997 and IW416.

The PM823 is an efficient low-cost power regulator. It consists of two 1.5 A buck regulators and one 525 mA LDO. The

LDO can be powered by the buck converter output (≥1.6 V) to minimize the power loss and simplify the system thermal

de-sign.

The PM823 is optimized for module applications. It minimizes the PCB footprint and BOM cost. The PM823 12-bump WLCSP

package provides the smallest footprint for the state-of-the-art module applications. For general-purpose

applications, the 24-pin QFN package can meet the low-cost PCB requirements. The QFN package also provides

additional functions such as power good outputs.

The PM823 dynamic voltage scaling (DVS) feature supports the latest SoC and processor power control scheme. The

PM823 also supports adaptive voltage scaling (AVS). The serial interface can be used to program the device to meet

different application requirements.
