PM823

Dual Synchronous 1.5A/1.5A Step-down Buck Regulators with 525ꢀmA LDO

Rev. 5 — 27 February 2024

Product data sheet

1 Product overview

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.

Features

• Supports 2.7 V~5.5 V operating voltage

• Two 1.5 A synchronous buck converters

• Single LDO supports up to 525 mA

• Ultra low 15 µA sleep current

• 3 MHz switching frequency

• High output voltage accuracy

• Supports both DVS and AVS

• Single wire proprietary serial interface

Package options

• QFN-24 lead (0.5 mm pin pitch)

Applications

• IoT devices

• Wi-Fi modules

• Smart home devices

• Cameras, printers

• Smart appliances

• Wi-Fi hubs, Access Points (APs)

• Set top boxes
