MP172
700 V Non-Isolated Off-Line Regulator Up to 120 mA Output Current
NOT RECOMMENDED FOR NEW DESIGNS. REFER TO MP172A
DESCRIPTION
FEATURES
R MP172 is a primary-side regulator that provides
accurate constant voltage (CV) regulation
O without an opto-coupler. It supports buck, boost, F buck-boost, and flyback topologies. It has an
Primary-Side CV Control, Supporting Buck, Boost, Buck-Boost, and Flyback Topologies
Integrated 700 V MOSFET and Current Source
integrated 700 V MOSFET to simplify the structure and reduce costs. These features make it an ideal regulator for off-line, low-power
D applications, such as home appliances and
standby power.
E MP172 is a green-mode-operation regulator. D Both the peak current and the switching S frequency decrease as the load decreases.
