The Future of Analog IC Technology
MP157
Smallest Energy Efficient Off-line
Regulator with Extended Power Range
DESCRIPTION
MP157 is a primary side regulator providing
accurate constant voltage (CV) regulation
without the Opto-coupler. It supports Buck,
Buck-Boost, Boost and Flyback topologies. A
500V MOSFET is integrated in the regulator, so
very simple structure and low cost can be
achieved. These features make MP157 an ideal
solution for off-line low power applications.
Typical applications include home appliance,
standby power and industrial control.
MP157 is a green mode operation regulator.
When the load decreases, the peak current and
the switching frequency decrease with the load.
As a result, it still offers excellent efficiency
performance at light load, thus better average
efficiency is achieved.
MP157 features various protections like
Thermal Shutdown (TSD), VCC under Voltage
Lockout (UVLO), Over Load Protection (OLP),
Short Circuit Protection (SCP), Open Loop
Protection.
MP157 is available in the TSOT23-5 and
SOIC8 packages.
