MP171AGS-P Monolithic Power Systems

MP171A 700V, Non-Isolated, Offline Regulator, Up to 60mA Output Current with Improved EMI Performance DESCRIPTION FEATURES The MP171A is a primary-side regulator that Primary-Side CV Control provides accurate constant voltage (CV) Supports Buck, Boost, Buck-Boost, and regulation without an optocoupler. It supports Flyback Topologies buck, boost, buck-boost, and flyback Integrated 700V MOSFET and Current topologies. Source Under 30mW No-Load Power Consumption The devices integrated 700V MOSFET Up to 2W Output Power simplifies the structure and reduces cost. This Maximum DCM Output Current below feature optimizes the device for offline, low- 40mA power applications such as home appliances and standby power. Maximum CCM Output Current below 60mA The MP171A is a green-mode operation Low VCC Operating Current regulator. Both the peak current and switching Frequency Foldback frequency lower as the load decreases. This Limited Maximum Frequency feature provides excellent efficiency at light load, Peak Current Compression and improves the overall efficiency. Internally Biased VCC Protection features include thermal shutdown TSD, UVLO, OLP, SCP, Open-Loop (TSD), VCC under-voltage lockout (UVLO), Detection overload protection (OLP), short-circuit Available in TSOT23-5 and SOIC-8 protection (SCP), and open-loop detection. Packages The MP171A is available in TSOT23-5 and APPLICATIONS SOIC-8 packages. Home Appliances, White Goods, and Consumer Electronics Industrial Controls Standby Power All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.
