MIC4802

High Efficiency 800mA Single Channel

Linear WLED Driver with

Ultra Fast PWM™ Control

General Description

Features

The MIC4802 is a high efficiency White LED (WLED)

driver designed to drive a single LED up to 800mA. The

MIC4802 constant current driver is designed to drive high

power LED’s in various lighting applications. The MIC4802

provides the highest possible efficiency as this architecture

has no switching losses present in traditional charge

pumps or inductive boost circuits. It features a typical

dropout of 280mV at 800mA. This allows the LEDs to be

driven directly from the voltage source eliminating

switching noise/losses present with the use of boost

circuitry. The high accuracy (±1% Typical) current

regulated WLED channel ensures uniform display

illumination under all conditions. The brightness is

controlled through an Ultra Fast PWM™ Control interface

operating down to less than 1% duty cycle.

• High Efficiency (no Voltage Boost losses)

• Ultra Fast PWM™ control (200Hz to 500kHz)

• Input voltage range: 3.0V to 5.5V

• Dropout of 280mV at 800mA

• Programmable LED current with external resistor

• Current accuracy of ±1% typical

Applications

• Bill board displays

• Marquee displays

• Instrument displays

• Architectural lighting

The MIC4802 is available in the 8-pin SOIC Epad package

with a junction temperature range of -40°C to +125°C.
