MP174 700V Non-Isolated Regulator up to 400mA Output Current

Product Detail

MP174 is a primary-side regulator that provides accurate constant voltage (CV) regulation without opto-coupler. It supports Buck, Buck-Boost, Boost and Flyback topologies. It has an integrated 700V MOSFET to simplify the structure and reduce costs. These features make it an ideal regulator for off-line low power applications, such as home appliances and standby power. MP174 is a green-mode operation regulator. Both the peak current and switching frequency decrease as the load decreases. This feature provides excellent efficiency at light load, and improves the overall average efficiency. MP174 features various protections, including thermal shutdown (OTP), VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open loop protection. MP174 is available in small TSOT23-5 package and SOIC8 package.
