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.
