The device controls the flyback power stage and an external N-channel MOSFET to regulate system supply voltage and the LED current loop with integrated 4-string LED current balancing. With a 4V to 16V input voltage, the device outputs a direct driving signal to control the N-channel MOSFET for regulating the system supply voltage. The device also outputs a compensation signal to control the primary-side flyback (or other power stage) through an optocoupler. The MP4657B induces PWM dimming or analogue dimming to the LED current through the ADIMP\/PWM pin. Soft switching for the N-channel MOSFET can be achieved to reduce voltage spikes. When the PWM signal is ineffective, the device directly controls the system voltage through the flyback power stage. Applications include LCD monitors and TVs, desktop LCD flat panel displays and flat panel video displays. \u003cul\u003e \u003cli\u003eSingle stage flyback for high efficiency LED current and system voltage regulation\u003c\/li\u003e \u003cli\u003eIndividual control method for the LED driver stage and system voltage stage\u003c\/li\u003e \u003cli\u003e4-string, 80V LED current balancing\u003c\/li\u003e \u003cli\u003e1.5% system voltage accuracy, 1.5% LED current accuracy and 2% LED current balancing\u003c\/li\u003e \u003cli\u003eHigh efficiency, low LEDx regulation voltage\u003c\/li\u003e \u003cli\u003eFast dynamic control, fast response, system supply overvoltage protection (OVP)\u003c\/li\u003e \u003cli\u003eSystem supply short protection, LED open\/LED short protection, LEDx pin short to ground protection\u003c\/li\u003e \u003cli\u003eFeedback open loop protection for system voltage\u003c\/li\u003e \u003cli\u003eSoft switching for the external N-channel MOSFET\u003c\/li\u003e \u003cli\u003eThermal protection\u003c\/li\u003e \u003c\/ul\u003e Footnotes MPS part numbers ending in \"-P\" and \"-Z\" are the same parts.
