MPS MP157 EasyPower voltage converters are primary-side regulators which provide accurate and constant voltage (CV) regulation without the Opto-coupler. MP157 supports Buck, Buck-Boost, Boost and Flyback topologies. These regulators are integrated with 500V MOSFET for simple structure and low cost making MP157 ideal for off-line low power applications including home appliance, standby power, and industrial control. When the load decreases, the peak current and the switching frequency decrease with the load. As a result, MP157 still offers excellent efficiency performance at light load, and better average efficiency is achieved. MPS MP157 EasyPower voltage converters feature various protections like Thermal Shutdown (TSD), VCC under Voltage Lockout (UVLO), Over Load Protection (OLP), Short Circuit Protection (SCP), Open Loop Protection. MP157 is available in the TSOT23-5 and SOIC8 packages.
