MP2480

5V―36V Input, 3A High

Power LED Driver

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2480 is step-down switching regulator

that delivers a constant current of up to 3A to

high-power LEDs. It integrates a high-side,

high-voltage power MOSFET with a current limit

of 4.3A. The wide 5V to 36V input range

•

Wide 5V to 36V Operating Input Range

Up to 95% Efficiency

Hysteretic Control with No Compensation

No Output Capacitor Required

±3% LED Current Accuracy

Up to 2MHz Switching Frequency

Up to 20kHz Dimming Frequency

200mV Reference Voltage

Short-Circuit Protection with Integrated

High-Side MOSFET

Thermal Shut Down

accommodates

variety of step-down

applications, making it ideal for general lighting

and LCD backlighting applications. Hysteretic

current-mode control helps provide for a very

fast response, which makes the 20kHz dimming

frequency possible. MPS’s proprietary feedback

control minimizes the number of external

components while delivering an LED current

with a typical accuracy of ±3%.

•

Available in SOIC8-EP

APPLICATIONS

The switching frequency goes up to 2MHz, thus

permitting smaller components. Thermal shut

down, and short circuit protection provide
