DIO5718P

High Efficiency, 28 V, 2.0 A Sychronous Step-Down

Regulator for Dimmable LED Driver

Features

Descriptions

The DIO5718P is a high efficiency synchronous

step-down LED regulator that achieves up to 2.0 A

output current. It operates at 1 MHz and integrates

two very low R_DS(ON)power switches to minimize

and reduce the external components.



Wide input range: 4.5 V ~ 28 V

Up to 2.0 A output current capability

Low R_DS(ON)for internal switches

High side / low side: 125 mΩ / 75 mΩ

Fixed 1 MHz switching frequency

Cycle by cycle 2.8 A valley current limit for

low side



It supports PWM dimming duty 1% ~ 100% to

achieve dimmable LED lighting application.



High accuracy for low dimming scale

Analog dimming with PWM input

Over temperature protection

Applications



DVR or NVR (IP camera) system application

Compact package: TSOT23-6, DFN2*1.5-6



24VDC lighting
