The Future of Analog IC Technology
DESCRIPTION
MP150 is a primary-side regulator that provides
accurate constant voltage (CV) regulation
without the opto-coupler, and supports Buck,
Buck-boost, Boost and Flyback topologies. It
has an integrated 500V MOSFET that simplifies
the structure and reduces costs. These features
help to make it a competitive candidate for off-
line low power applications, such as home
appliances and standby power.
MP150 is a green-mode operation regulator.
Both the peak current and switching frequency
decrease as the load decreases to provide
excellent efficiency performance at light load,
thus improving the overall average efficiency.
The
MP150
features
including thermal shutdown (TSD), VCC under-
voltage lockout (UVLO), over-load protection
(OLP), short-circuit protection (SCP), and open
loop protection.
MP150 is available in the TSOT23-5 and
SOIC8 packages.
