The MP3314 is a 6-channel white LED (WLED) driver that operates from a 3V to 30V input voltage (V_IN) range. The MP3314 applies six internal current sources in each LED string terminal. The maximum current for each channel is 60mA. The MP3314 is designed to drive WLED arrays for LCD panels in tablets and notebook backlighting applications.

Peak current mode control and pulse-width modulation (PWM) control are employed to regulate the boost converter’s output voltage (V_OUT). The MP3314 integrates a digital serial interface that can configure the device parameters, such as the operation mode, switching frequency (f_SW), dimming mode, dimming duty, phase shift, frequency spread spectrum (FSS), and various protection thresholds.

The device supports a configurable switching slew rate and FSS function to reduce EMI. The MP3314 achieves high efficiency with a low headroom voltage for LED regulation and a low MOSFET on resistance (R_DS(ON)). Full protection features include LED open protection, LED short protection, over-current protection (OCP), over-voltage protection (OVP), and over-temperature protection.

The MP3314 is available in QFN-24 (4mmx4mm) and CSP-20 (2.4mmx1.74mm) packages.
