The Future of Analog IC Technology
DESCRIPTION
The MP3312 is a dual-channel step-up WLED
driver with integrated 40V MOSFET, and
supports 2.7V to 5.5V power supply input. It
uses peak current mode to regulate the LED
current which is set by external resistor.
The MP3312 employs 1.2MHz fixed switching
frequency. It features supporting both PWM
input analog dimming and digital analog
dimming to accurately regulate the dimming
current.
The MP3312 integrates current source to
balance LED current, which leads good ILED
matching and accuracy performance.
In addition, the MP3312 has LED open and
short protection, cycle by cycle current limit
protection, and thermal shutdown protection. It
is available in tiny WLCSP1.3X 1.3-9 package.
