MAP3201 Datasheet – Current Switch Mode PWM LED Driver

Part Number: MAP3201, MAP3201SIH, Marking : SELC2010M

Function: High Current Switch Mode PWM LED Driver

Package : 16 Leads SOIC type

Manufacturer: MagnaChip Semiconductor ( )



The MAP3201 is a high efficiency current mode PWM driver. It is designed for LED driver that is used as the light source of LCD panel. The controller can achieve efficiency higher than 90% for buck and boost applications. The MAP3201 for accurate LED dimming control use external PWMI signal and set internal frequency by external resistor which is programmable.

The MAP3201 has a stable operation with wide input voltage because it can be operated as separated VCC with input voltage It has a auto-restart recovery protection if the system occur fault signal. it can provide a good safety features.
