MP156
Small, Energy-Efficient, Off-line Regulator
30mW No-Load Power Consumption
DESCRIPTION
MP156 is a primary-side regulator that provides
accurate constant voltage (CV) regulation
without opto-coupler, support Buck, Buck-Boost,
Boost and Flyback topologies. It has an
integrated 500V MOSFET to simplify the
structure and reduce costs. These features
make it a competitive candidate for off-line low
power applications, such as home appliances
and standby power.
MP156 is a green-mode-operation regulator.
Both its the peak current and the switching
frequency decrease as the load decreases to
provide excellent efficiency at light load, thus
improving the overall average efficiency.
MP156 features various protections, including
thermal shutdown (TSD), VCC under-voltage
lockout (UVLO), overload protection (OLP),
short-circuit protection (SCP), and open loop
protection.
MP156 is available in the TSOT23-5 and
SOIC8 packages.
