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
