• Extendable LED Channels that Share One Power Stage Set
• TSSOP28EP and SOIC28 Packages

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. The fault flag pin indicates the statuses of all fault signals. The MP3393 can be daisy-chained to expand the number of LED channels. It is available in TSSOP28EP and SOIC28 packages.
