EM5812A

12A 5V/12V Step-Down Converter EM5812/A General Description EM5812/A is a synchronous rectified PWM controller with a built in high-side power MOSFET operating with 5V or 12V supply voltage. It achieves 10A continuous output current with excellent load and line regulation. This device operates at 200/300kHz and provides an optimal level of integration to reduce size and cost of the power supply. This part includes internal soft start, internal compensation networks, over current protection, under voltage protection, and shutdown function. This part is available in SOP-8 package.
