The MP3385B employs peak current control mode and pulse-width modulation (PWM) control architecture for system loop regulation. The MP3385B drives an external MOSFET to boost the output voltage (VOUT) from a 4.5V to 33V input voltage (VIN) supply. The MP3385B provides an I2C digital interface to flexibly set the operation and protection modes, including dimming mode, the dimming current and dimming ratio, overcurrent protection (OCP), overvoltage protection (OVP), the LED short protection threshold, and the switching frequency (fSW). For ease of use and board debugging, the MP3385B automatically detects and disables the unused LED strings during start-up to avoid charging the output to the OVP threshold. Applications include desktop LCD flat-panel displays, all-in-one PCs, 2D and 3D LCD TVs. \u003cul\u003e \u003cli\u003e4-string, max 300mA\/string WLED driver, 4.5V to 33V input voltage (VIN) range\u003c\/li\u003e \u003cli\u003e80V absolute maximum rating for each string, 1.8% current matching accuracy between each string\u003c\/li\u003e \u003cli\u003eUnused channel auto-detection during start-up, 100KHz to 900KHz configurable switching frequency\u003c\/li\u003e \u003cli\u003eMultiple dimming modes selectable via the I2C interface\u003c\/li\u003e \u003cli\u003e2% to 100% configurable full-scale current with 8bit resolution\u003c\/li\u003e \u003cli\u003e0.15V to 0.5V latch-off and recoverable overcurrent protection (OCP) threshold, 50mV\/Step\u003c\/li\u003e \u003cli\u003eRecoverable thermal shutdown protection\u003c\/li\u003e \u003cli\u003e18V to 80V overvoltage protection (OVP), 2V\/step\u003c\/li\u003e \u003cli\u003e0% to 100% LED dimming range with 10bit resolution for internal dimming mode\u003c\/li\u003e \u003cli\u003eAvailable in a QFN-20 package\u003c\/li\u003e \u003c\/ul\u003e Footnotes MPS part numbers ending in \"-P\" and \"-Z\" are the same parts.
