MP4688

80V Input, 1A High

Power LED Driver

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP4688 is a high voltage input step-down

switching regulator to deliver a constant current of

up to 1A to high power LEDs. It integrates a high-

side high voltage power MOSFET with a current

limit of 3.2A (typical value). The wide 4.5V to 80V

input range accommodates a variety of step-down

applications, making it ideal for automotive,

industry and general lighting applications.

Hysteresis current mode control is applied for

very fast response, which makes the 20kHz

dimming frequency possible. MPS’s proprietary

feedback control scheme minimizes the number

of external components while delivering a LED

current with typical ±5% accuracy.

•

Wide 4.5V to 80V Operating Input Range

No Output Capacitor Required

±5% LED Current Accuracy

Hysteretic Control: No Compensation

Up to 2MHz Switching Frequency

Up to 20kHz Dimming Frequency

Dedicated PWM Dimming Control Input

Short circuit protection with integrated high

side MOSFET

Optional Output Voltage Limitation

Thermal shut down

200mV reference voltage for high efficiency

Up to 95% Efficiency

•

170μA Quiescent Current

Available in SOIC8 and SOIC8 with

Exposed Pad Packages

The switching frequency is up to 2MHz, thus

allowing for small component size. The thermal

shut down, short circuit protection, and optional

output voltage limitation provide reliable, fault

tolerant operations. A 170µA quiescent current

allows its use in battery-powered applications.

APPLICATIONS

•

High Power LED Driver

Automotive, Industry and General Lighting

Constant Current Source

The MP4688 is available in SOIC8 and SOIC8

with exposed pad packages.

All MPS parts are lead-free and adhere to the RoHS directive. For MPS green
