MAP3201SIH

High current switch mode PWM LED Driver

MagnaChip Semiconductor 

General Description

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.

Multiple MAP3201 have synchronized to each others or to other

external clock which is generated by Sync Pin.

The MAP3201 provide a 0.4A source current and 0.8A Sink

current gate driver. This can be suitable for high power

application. Using BCD process, the MAP3201 has a good

immunity at switching noise.

The MAP3201’ application can be so easy to making lowest cost

system.

The MAP3201 is available in 16-Lead SOIC package and it is

offered in Halogen-free (fully RoHS compliant).
