MP3301

1.3MHz, 700mA, Fixed-Frequency

Step-Up Driver for up to 10 White LEDS

DESCRIPTION

FEATURES

The MP3301 is a step-up converter designed to

drive WLEDS arrays from a single-cell, lithium-ion

battery. The MP3301 uses a current-mode, fixed-

frequency architecture to regulate the LED

current, which is measured through an external

current sense resistor. Its low 200mV feedback

voltage reduces power loss and improves

efficiency. The MP3301 turns off in the presence

of an open-circuit over-voltage condition.



Internal Power MOSFET

Drives up to 10 White LEDs in Series

Up to 89% Efficiency

PWM and Analog Dimming

1.3MHz Fixed Switching Frequency

Low 200mV Feedback Voltage

Internal 700mA Current Limit

Open-Load Shutdown

UVLO, Thermal Shutdown

Available in TSOT23-5 Packages

The MP3301 includes under-voltage lockout,

current limiting, and thermal-overload protection

to prevent damage in the event of an output

overload.

APPLICATIONS



Smart Phones

Digital Still Cameras

Small LCDs

The MP3301 is available in a small 5-pin TSOT23

package.
