HVLED002

High performance current mode LED controller

Datasheet

- production data

Features

 Trimmed oscillator for precise frequency

control

 Oscillator frequency guaranteed at 250 kHz

 Current mode operation to 500 kHz

 Latching PWM for cycle-by-cycle current

limiting

 Internally trimmed reference with undervoltage

lockout

 High current totem pole output

 Undervoltage lockout with hysteresis

 Low start-up and operating current

Description

The HVLED002 control IC provides the necessary

features to implement off-line or DC to DC fixed

frequency current mode control schemes to

implement LED drivers. Internally implemented

circuits include a trimmed oscillator for the precise

duty cycle control, undervoltage lockout,

a precision reference trimmed for accuracy at the

error amplifier input, a PWM comparator which

also provides current limit control and a totem

pole output stage designed to the source or sink

high peak current. The output stage, suitable for

driving N-channel MOSFETs, is low in the off-

state.
