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. 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.
