MP156
Small, Energy-Efficient, Off-line Regulator
30mW No-Load Power Consumption
The Future of Analog IC Technology
DESCRIPTION FEATURES
Primary-side constant voltage (CV) control,
MP156 is a primary-side regulator that provides
supporting Buck, Buck-Boost, Boost and
accurate constant voltage (CV) regulation
Flyback topologies
without opto-coupler, support Buck, Buck-Boost,
Integrated 500V/20 MOSFET
Boost and Flyback topologies. It has an
<30mW no-load power consumption
integrated 500V MOSFET to simplify the
structure and reduce costs. These features Up to 4W output power
make it a competitive candidate for off-line low
Maximum DCM output current less than
power applications, such as home appliances 130mA
and standby power.
Maximum CCM output current less than
220mA
MP156 is a green-mode-operation regulator.
Low VCC Operating Current
Both its the peak current and the switching
Frequency foldback
frequency decrease as the load decreases to
Limited maximum frequency
provide excellent efficiency at light load, thus
Peak-current compression
improving the overall average efficiency.
Internal high-voltage current source
MP156 features various protections, including
Internal 350ns leading-edge blanking
thermal shutdown (TSD), VCC under-voltage
Thermal shutdown (auto restart)
lockout (UVLO), overload protection (OLP),
VCC under voltage lockout with hysteresis
short-circuit protection (SCP), and open loop
Timer based over-load protection.
protection.
Short-circuit protection
MP156 is available in the TSOT23-5 and
Open-loop protection
SOIC8 packages.
