MP24830

4.5V – 90V, Programmable Frequency

White LED Driver

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP24830 is a 90V white LED driver

suitable for either step-down or inverting

step-up/down applications. It supports a wide

input range with excellent load and line

regulation. Its programmable current limit

provides customized applications with a wide

power range. Current mode operation provides

a fast transient response and eases loop

stabilization. Fault condition protection includes

thermal shutdown, cycle-by-cycle peak-current

limiting, open-string protection, and output

short-circuit protection.



Programmable Maximum Output Current

Unique Step-Up/Down Operation (Buck-

Boost Mode)

Wide 4.5V-to-90V Operating Input Range

for Step-Down Applications (Buck Mode)

Adjustable Switching Frequency

Analog and PWM Dimming

0.2V Reference Voltage



10μA Shutdown Mode

No Minimum LED Quantity Required

Stable with Low ESR Output Ceramic

Capacitors

The MP24830 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.



Cycle-by-Cycle Over-Current Protection

Thermal Shutdown Protection

Open-String Protection

Output Short-Circuit Protection

Available in 14-Pin SOIC and QFN

Packages

The MP24830 requires a minimal number of

readily-available external components. It is

available in 14-pin SOIC and QFN packages.

APPLICATIONS



General LED Illumination

Automotive LED Lighting

LCD Backlight
