SY7203 30V High Current Boost LED Driver

SY7203 develops a step-up DC/DC converter that delivers an accurate constant current for driving LEDs. Operating at a fixed switching frequency of 1MHz allows the device to be used with small value external ceramic capacitors and inductor. The LED current is programmable through the external resist.

SY7203 Features

* Input voltage range: 2.8 to 30V

* Switch current limit: 4A

* Drives LED strings up to 30V

* 1MHz fixed frequency minimizes the external components

* 20kHz~1MHz wide dimming frequency range for EN/PWM pin

* Internal softstart limits the inrush current
