LED Driver PR4101

High Power LED Buck Driver

The PR4101 is a LED buck driver for driving one

or several high power LEDs in series. The

supply voltage can be up to 40 V, with an

output current of more than 1 A using an

external

n-channel

MOSFET

switching

transistor. The PR4101A with additional PWM and

power down input is delivered SOP14 packaged,

while the PR4101B is offered SO8 packaged.

FEATURES

• Adjustable output current of several amps

• Supply voltage up to 40 V

• Dimming with phase-cut dimmer

• Brightness control with PWM (PR4101A only)

• Output current temperature compensation

• Delayed start possible (PR4101A only)

• Over temperature protection

• Frequency spreading for improved EMI

• Low standby current of < 35 µA

• Under voltage lockout

APPLICATIONS

• Halogen lamp or filament bulb replacement by

LEDs

• General illumination

• Warning lights

• Automotive lighting

• Indicator signs

• LCD backlighting
