RT5796D

1.5A, 1MHz, 6V CMCOT Synchronous Step-Down Converter

Features

 Efficiency Up to 95%

General Description

The RT5796D is a high efficiency synchronous

 R_DSON160m HS / 110m LS

step-down DC/DC converter. Its input voltage range is

 V_INRange 2.5V to 6V

from 2.5V to 6V and provides an adjustable regulated

 V_REF0.6V with 2% Accuracy

output voltage from 0.6V to 3.4V while delivering up to

 CMCOT™ Control Loop Design for Best

1.5A of output current.

Transient Response, Robust Loop Stability with

The internal synchronous low on-resistance power

switches increase efficiency and eliminate the need for

an external Schottky diode. The Current Mode

Constant-On-time (CMCOT) operation with internal

compensation allows the transient response to be

optimized over a wide range of loads and output

capacitors. The RT5796D is available in the

TSOT-23-5 and TSOT-23-6 packages.

Low-ESR (MLCC) C_OUT

 Fixed Soft-Start 1.2ms; PGOOD Function in

TSOT-23-6

 Cycle-by-Cycle Over Current Protection

 Input Under Voltage Lockout

 Output Under Voltage Protection (UVP Hiccup)

 Thermal Shutdown Protection

Applications

Ordering Information
