HM5669 Product details

Description

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

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.
Open LED over voltage protection.
