MP24833

3A, 55V

White LED Driver

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP24833 is a 55V, 3A, white LED driver

suitable for step-down, inverting step-up/down

and step-up applications. It achieves 3A output

current over a wide input supply range with

excellent load and line regulation. Current mode

operation provides fast transient response and

eases loop stabilization. Fault condition



3A Maximum Output Current

Unique Step-Up/Down Operation (Buck-

Boost Mode)

Wide 4.5V-to-55V Operating Input Range

for Step-Down Applications (Buck Mode)

0.19Ω Internal Power MOSFET Switch

Fixed 200kHz Switching Frequency

Analog and PWM Dimming



protection

includes

thermal

shutdown,

cycle-by-cycle peak current limiting, open strings

protection and output short circuit protection.

0.198V Reference Voltage

6μA Shutdown Mode

The MP24833 incorporates both DC and PWM

dimming onto a single control pin. The separate

input reference ground pin allows for direct

enable and/or dimming control for a positive to

negative power conversion.

No Minimum Number of LEDs Required

Stable with Low ESR Output Ceramic

Capacitors

Cycle-by-Cycle Over-Current Protection

Thermal Shutdown Protection

Open Strings Protection



The MP24833 requires a minimal number of

readily-available standard external components

and is available in an SOIC8E package.

Output Short-Circuit Protection

Available in an SOIC8E Package

APPLICATIONS
