The EV172-J-00A Evaluation Board is designed to demonstrate the capabilities of MP172. The MP172 is a primary-side constant voltage regulator providing accurate constant voltage (CV) regulation without Opto-coupler. It supports Buck, Buck-Boost, Boost and Flyback topologies.

The EV172-J-00A Evaluation Board is designed as Buck application. EV172-J-00A typically drives 5V/50mA load from 85VAC to265VAC, at 60/50Hz.

The EV172-J-00A has an excellent efficiency and meets 2kV IEC61000-4-5 surge immunity and EN55022 conducted EMI requirements. MP172 features various protections, including thermal shutdown (TSD), VCC under-voltage lockout (UVLO), over-load protection (OLP), short- circuit protection (SCP), and open loop protection.

EV172-J-00A is the Evaluation Board for MP172 TSOT23-5 package type.

700V Non-Isolated Regulator up to 120mA Output Current

MP172 is a primary-side regulator that provides accurate constant voltage (CV) regulation without an opto-coupler. It supports buck, boost, buck-boost, and flyback topologies. It has an integrated 700 V MOSFET to simplify the structure and reduce costs. These features make it an ideal regulator for off-line, low-power applications, such as home appliances and standby power. MP172 is a green-mode operation regulator. Both the peak current and the switching frequency decrease as the load decreases. This feature provides excellent efficiency at light load and improves the overall average efficiency. MP172 has various protection features including thermal shutdown (TSD), VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open-loop protection. MP172 is available in a small TSOT23-5 package and SOIC-8 package.
