ADD5207 Datasheet White Led Driver

Manufacturer: Analog Devices

Overview: Data Sheet.

Datasheet Details

The ADD5207 is a white LED driver for backlight applications based on high efficiency, current mode, step-up converter technology.

It is designed with a 0.15 Ω, 1.5 A internal switch and a pin-adjustable operating frequency between 600 kHz and 1 MHz.

The ADD5207 contains four regulated current sources for uniform LED brightness.

White LED driver based on inductive boost converter Integrated 40 V MOSFET with 1.5 A peak current limit Input voltage range: 6 V to 21 V Maximum output adjustable up to 36 V 600 kHz to 1 MHz adjustable operating frequency Typical 39 V fixed overvoltage protection (OVP) Built-in soft start for boost converter Drives up to 4 LED current strings LED current adjustable up to 25 mA for each channel Headroom control to maximize efficiency Fixed LED dimming frequency: 8 kHz LED open fault protection B.
