Realizing high-efficiency and downsizing IPD for switching power supply MIP521A) Overview MIP521A is suitable for standby power supplies of TVs, main power supply for white goods, etc. Energy consumption is reduced to less than 30mW(@240V at no load), which makes it easier to meet energy efficiency regulations such as ErP, Energy Star, GB. Newly developed power MOSFET withstanding voltage of 800V realizes the reduction of energy loss by snubber circuit. Built-in frequency jitter function can reduce average EMI noise and get rid of EMI filter cost. Protection function of over voltage/load/temperature can achieve the safety.
