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
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.
