The EV3314-R-00A is an evaluation board designed to demonstrate the capabilities of the MP3314, a boost converter with six channel current sources that drives WLED arrays for LCD panels in tablets and notebook backlighting applications.

The MP3314 supports a 3V to 30V input voltage (V_IN) range and an output voltage (V_OUT) up to 43V. The device uses peak current mode control and pulse-width modulation (PWM) control to maintain boost converter regulation. The six integrated LED current source channels support a maximum of 60mA per channel.

The MP3314 employs a standard digital interface to set the operation mode, switching frequency (f_SW), dimming mode and duty, phase shift, spread spectrum, and various protection thresholds. To improve EMI performance, the MP3314 supports a configurable switching slope and spread spectrum function. The device also features high efficiency due to a low headroom voltage for LED regulation and the switching MOSFET’s small on resistance (R_DS(ON)).

For system reliability, the MP3314 integrates rich protection features, including 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. The EV3314-R-00A is a fully assembled evaluation board.
