General Description VAS1350 is a PFM mode boost LED driver with external power MOSFET. By adjusting external sense resistor, VAS1350 can deliver up to several amperes output current and suitable for high power LED array applications. VAS1350 operates from a 5V to hundreds of voltages input range. Its overvoltage protection can avoid damage to circuit of open load and a dedicated analog input (ADJ) enables a wide range of analog dimming from 0.5V to 2.4V. VAS1350 provide excellent protection functions, such as MOSFET over current protection, ROVP short to ground protection, UVLO and over heat protection, LED open protection. VAS1350 is available with SOP8 package
Features 10V gate driver Multiple protections • OVP short-to-GND protection • Output over voltage protection • Over temperature protection Wide input range up to hundreds of voltages in system No compensation capacitors Application Landscape lighting Street lamp Indoor LED lighting LED backlighting
