RT8810DGQW

Overview

The RT8810DGQW is a dual-phase synchronous buck PWM controller manufactured by Richtek USA Inc. It operates within an input voltage range of 4.5V to 26V and supports switching frequencies between 100 kHz and 1 MHz. The device provides four output channels with adjustable output voltages from 400 mV to 2.5 V and delivers up to 1.5 A per phase. It features a maximum duty cycle of 80% and functions reliably across a temperature range of -40°C to +85°C. The component is housed in a WQFN-24 package.

Feature Summary

Dual-phase architecture for enhanced power delivery
Synchronous rectification for improved efficiency
Adjustable switching frequency control
Integrated current limit and soft-start protection

Applications

Portable devices requiring efficient power management
Industrial equipment power supplies
