SY7201 30V High Current Boost LED Driver

SY7201 and SY7201A are DC/DC step-up converters that deliver an accurate constant current for driving LEDs. Operation at a fixed switching frequency of 1MHz allows the device to be used with small value external ceramic capacitors and inductor. LEDs connected in series are driven with a regulated c.

SY7201 Features

* Input voltage range: 2.8 to 30V

* Switch current limit 2A

* Drives LED strings up to 30V

* 1MHz fixed frequency minimizes the external components

* Dimming frequency for EN/PWM pin: ο SY7201: 20kHz~1MHz ο SY7201A: 100Hz~10kHz

* Internal softstart lim
