HM5669 step-up DC/DC converter

HM5669 Description

HM5669 General .
HM5669 develops a step-up DC/DC converter that delivers an accurate constant current for driving LEDs.

HM5669 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
