Product Description

The EV172A-J-00A Evaluation Board is designed to demonstrate the capabilities of the MP172A. The MP172A is a primary-side constant voltage regulator, which provides accurate constant voltage (CV) regulation without opto-coupler. It supports Buck, Buck-Boost, Boost and Flyback topologies.

The EV172A-J-00A Evaluation Board is designed as Buck application. It typically drives 5V/120mA load from 85VAC to 265VAC input.

The EV172A-J-00A has an excellent efficiency and meets class3 (2kV) IEC61000-4-5 surge immunity and EN55022 conducted EMI requirements. The radiation emission performance gets improved compared with the MP172. The MP172A features various protections, including thermal shutdown (TSD), VCC under-voltage lockout (UVLO), over-load protection (OLP), short-circuit protection (SCP), and open loop detection.

The MP172A is available in TSOT23-5 and SOIC-8 packages.

Parametrics


700V, Non-Isolated, Offline Regulator, Up to 120mA Output Current with Improved EMI Performance

The MP172A is a primary-side regulator that provides accurate constant voltage (CV) regulation without an optocoupler. It supports buck, boost, buck-boost, and flyback topologies.

The device’s integrated 700V MOSFET simplifies the structure and reduces cost. This feature optimizes the device for offline, low-power applications such as home appliances and standby power.

The MP172A is a green-mode operation regulator. Both the peak current and switching frequency lower as the load decreases. This feature provides excellent efficiency at light load, and improves the overall average efficiency.

Protection features include thermal shutdown (TSD), VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open-loop detection.

The MP172A is available in TSOT23-5 and SOIC-8 packages.
