The Future of Analog IC Technology
MP174
700V Non-Isolated Off-Line Regulator,
Up to 400mA Output Current
DESCRIPTION
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.
