MP174A 700V Non-Isolated Off-Line Regulator, Up to 400mA Output Current with Improved EMI Performance DESCRIPTION FEATURES Primary-Side CV Control, supporting Buck, The MP174A is a primary-side regulator that Buck-Boost, Boost, and Flyback Topologies provides accurate constant voltage (CV) Integrated 700V/13.5 MOSFET and regulation without an opto-coupler. It supports Current Source buck, buck-boost, boost, and flyback topologies. <30mW No-Load Power Consumption It has an 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 The MP174A is a green-mode-operation Low VCC Operating Current regulator. Both the peak current and switching Frequency Foldback frequency decrease as the load decreases. Limited Maximum Frequency This feature provides excellent efficiency at light Peak-Current Compression load and improves the overall average Internally Biased VCC efficiency. OTP, UVLO, OLP, SCP, Open-Loop The MP174A has various protection features, Detection including thermal shutdown (OTP), VCC under- voltage lockout (UVLO), over-load protection APPLICATIONS (OLP), short-circuit protection (SCP), and open- Home Appliances, White Goods and loop detection. Consumer Electronics The MP174A is available in a small TSOT23-5 Industrial Controls package and SOIC8 package. 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.
