MP174 700V Non-Isolated Off-Line Regulator, Up to 400mA Output Current The Future of Analog IC Technology DESCRIPTION FEATURES Primary-side CV control, supporting Buck, MP174 is a primary-side regulator that provides Buck-Boost, Boost and Flyback topologies accurate constant voltage (CV) regulation Integrated 700V/13.5 MOSFET and without opto-coupler. It supports Buck, Buck- current source Boost, Boost and Flyback topologies. It has an <30mW no-load power consumption integrated 700V MOSFET to simplify the structure and reduce costs. These features Up to 5W output power make it an ideal regulator for off-line low power Maximum DCM output current less than applications, such as home appliances and 250mA standby power. Maximum CCM output current less than 400mA MP174 is a green-mode-operation regulator. Low VCC Operating Current Both the peak current and switching frequency Frequency foldback decrease as the load decreases. This feature Limited maximum frequency provides excellent efficiency at light load, and Peak-current compression improves the overall average efficiency. Internally biased VCC MP174 features various protections, including OTP, UVLO, OLP, SCP, open loop thermal shutdown (OTP), VCC under-voltage protection lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open loop APPLICATIONS protection. Home appliances, white goods and MP174 is available in small TSOT23-5 package consumer electronics and SOIC8 package. Industrial controls Standby power All MPS parts are lead-free, halogen free, and adhere to the RoHS directive. For MPS green status, please visit MPS website under Quality Assurance.
