MP3398H Series Step-Up WLED Controllers

Monolithic Power Systems (MPS) MP3398H Series Step-Up WLED Controllers are designed to drive WLED arrays for large LCD panel backlighting applications. These step-up controllers feature four LED current channels and can be expanded in number with two or more ICs in parallel, sharing a single power source. The MP3398H WLED controllers employ peak current control mode with a fixed switching frequency (fSW) that is configurable via an external setting resistor. The MP3398H controllers drive an external MOSFET to boost the output voltage (VOUT) from a 4.5V to 33V input voltage (VIN) supply. These devices also regulate the current in each LED string to the value set by external current-setting resistors.
