【文字介绍】

MP156 is a primary-side regulator that provides


accurate constant voltage (CV) regulation


without opto-coupler, support buck, buck-boost,


or flyback topologies. It has an integrated 500V


MOSFET to simplify the structure and reduce


costs. These features make it a competitive


candidate for off-line low power applications,


such as home appliances and standby power.
