MP3313

MP3313

3-Channel, Max 38V Output, Linear/Exponential, Analog Dimming, Step-Up WLED Driver with I2C

Datasheet

Description

The MP3313 is a step-up, white, LED converter. The MP3313 uses peak-current mode and a 3-channel current sink to regulate the LED current with up to 25mA on each channel (100mA at flash mode) with 2.7 - 5.5V input voltage.
The MP3313 integrates a 300mΩ, 42V MOSFET and supports selectable over-voltage protection (17/23/30/38V). The MP3313 can drive up to 10 LEDs in series for LCD panels greater than 5”.
The MP3313 achieves ultra-high resolution analog dimming by converting the pulse-width input signal or internal register code to an 11-bit brightness code. The MP3313 is designed with two types of LED current dimming mapping: linear and exponential mapping.
An auto-switching frequency function is integrated to optimize efficiency performance. Full protection features include LED open and short protection, cycle-by-cycle current-limit protection, and thermal shutdown.
The I2C interface can set the internal register to program the MP3313 for flexible applications, such as dimming mode, LED current slope, and protection threshold.
The MP3313 is available in a small WLCSP-12 (1.3mmx1.7mm) package.
