Overview

LD7820 04/08/2012 Primary-Side PWM Controller with CV/CC Operation for LED REV:00 General Description The LD7820 is a primary-side feedback controller in CV/CC operation for LED lighting applications.
It minimizes the components counts and is available in tiny packages.
Those make it an ideal design for low cost applications.
The LD7820 provides constant voltage, constant current (CV/CC) operation requiring neither photo-coupler nor secondary control circuit.
Also, the LD7820 features OTP (Over Temperature Protection) and OVP (Over Voltage Protection) to prevent the circuit from being damaged under abnormal conditions.
Features  Primary-side Feedback Control  Constant Current Control  B...
