MP174A Datasheet | Monolithic Power Systems

DESCRIPTION The MP174A is a primary-side regulator that provides accurate constant voltage (CV) regulation without an 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. The MP174A 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. The MP174A has various protection features , including thermal shutdown (OTP), VCC undervoltage lockout (UVLO), over-load protection (OLP), short-circuit protection (SCP), and openloop detection. The MP174A is available in a small TSOT23-5 package and SOIC8 package.
