MIC4802YME More Semiconductors - ICs by Microchip Technology
800mA Single Channel WLED Driver w/ Ultrafast PWM Control
| Status: | Active |
|---|---|
| Series: | MIC4802 |
| RoHS: | Compliant |
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 LEDs 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 helps ensure 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.
The MIC4802 is available in the 8-pin SOIC Epad package with a junction temperature range of -40°C to +125°C.
