General Description

VAS1351 is a PFM mode Buck, Boost, Buck-Boost LED driver with external power MOSFET. By adjusting external sense resistor, VAS1351 can deliver up to several amperes output current and suitable for high power LED array applications.

VAS1351 operates from a 3V to hundreds of voltages input range. Its overvoltage protection can avoid damage to circuit of open load and a dedicated control loop.
