The Future of Analog IC Technology DESCRIPTION The MP3393 is a step-up controller with 8 current channel sources designed to power WLED backlights for large LCD panels. The MP3393 uses current-mode fixed-frequency architecture. It drives an external MOSFET to boost the output voltage. The switching frequency is programmable by an external setting resistor. The MP3393 integrates a constant-current control circuit to regulate the current in each LED string to the value set by an external current feedback resistor. Current matching can achieve 1.2% regulation accuracy between strings. Its low 202mV regulation voltage reduces power loss and improves efficiency. The MP3393 includes protections including under-voltage lockout, LED open/short protection, and thermal shutdown.
