Reference

Design

RT5795A

2A, 5.5V, Low I_QACOT Synchronous Step-Down Converter

General Description

Features

^2.5V to 5.5V Input Voltage Range

^Advanced COT Control loop design

^Fast Transient Response

The RT5795A is a full featured 5.5V, 2A, Advanced

Constant-On-Time (ACOT) synchronous step-down

converter with two integrated MOSFETs. The advanced

COT operation allows transient responses to be optimized

over a wide range of loads, and output capacitors to

efficiently reduce external component count. The RT5795A

provides up to 2.7MHz switching frequency to minimize

the size of output inductor and capacitors. The RT5795A

is available in the WDFN-8SL 2x2 package.

^Internal 100mΩ and 80mΩ Synchronous Rectifier

^Highly Accurate V_OUTRegulation Over Load/Line

Range

^Robust Loop Stability with Low-ESR C_OUT
