LED驱动器CAT4201应用
分享资料个
The CAT4201 is a step-down， easy-to-configure， dimmable LED driver. The package is a 5-pin SOT-23; with fewer than 10 discrete components （most of them surface mount）， the whole PCB can be small enough to fit into the base of an MR16 bulb. The voltage ratings on pins VBAT， CTRL and SW are 40 V， so driving 12 LEDs is possible with adequate voltage. The RSET pin determines the output DC current; CTRL is for dimming signal input. SW is the output of internal MOSFET.
The CAT4201 driver is strongly recommended for its compact circuitry and high efficiency making it ideally suited for the replacement of filament-based bulb， in applications such as spot light.
