EV150-J -00A –OFFLINE P RIMARY S IDE REGULATOR
DESCRIPTION
MP150 is a primary side regulator providing
accurate constant voltage (CV) regulation
without the Opto-coupler, support Buck, BuckBoost and Flyback topologies. 500V MOSFET
is integrated in the regulator, so very simple
structure and low cost can be achieved. These
features help to make it a competitive candidate
for off-line low power applications, such as
home appliance and standby power.
MP150 is a green mode operation regulator.
With the load decreasing, the peak current and
the switching frequency will both decreasing
with the load. As a result, it still offers excellent
efficiency performance at light load, thus better
average efficiency is achieved.
MP150 features various protections like
Thermal Shutdown (TSD), VCC under Voltage
Lockout (UVLO), Over Load Protection (OLP),
Short Circuit Protection (SCP), Open Loop
Protection.
