MP3306
30V, 700kHz Synchronous Step-Up
White LED Driver
DESCRIPTION
The MP3306 is a step-up converter designed for
driving white LEDs from 3V to 12V power supply.
The MP3306 uses current mode, fixed frequency
architecture to regulate the LED current, which is
measured through an external high-side current
sense resistor. The low 202mV feedback voltage
and synchronous rectification reduces power loss
and improves efficiency.
The MP3306 is turned off if an over-voltage
condition is present due to an open circuit
condition. The output disconnect feature allows
the output to be completely discharged. The
MP3306 includes under-voltage lockout, current
limiting, output short protection and thermal
overload protection.
The MP3306 is available in small 12-pin QFN
(2mm x 2mm) package.
