Product Description

The EV174A-J-00A Evaluation Board is designed to demonstrate the capabilities of MP174A. The MP174A 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 EV174A-J-00A Evaluation Board is designed as Buck application. EV174A-J-00A typically outputs 3.6W with a 12V/300mA load from 85VAC to 265VAC input.

The EV174A-J-00A has excellent efficiency and meets IEC61000-4-5 surge immunity and EN55022 conducted EMI requirements. Most of all, the radiation performance gets improved compared with MP174. MP174A features various protections, including thermal shutdown (TSD), VCC under-voltage lockout (UVLO),over-load protection (OLP), short-circuit protection (SCP), and open loop protection.

MP174AGJ is available in TSOT23-5 package.

Parametrics

700V, Non-Isolated Offline Regulator, Up to 400mA Output Current with Improved EMI Performance

The MP174A is a primary-side regulator that provides accurate constant voltage (CV) regulation without an opto-coupler. It supports buck, buck-boost, boost, and flyback topologies. It has an integrated 700V MOSFET to simplify the structure and reduce costs. These features make it an ideal regulator for offline, low-power applications such as home appliances and standby power.

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

The MP174A has various protection features, including thermal shutdown (OTP), VCC under-voltage lockout (UVLO), over-load protection (OLP), short-circuit protection (SCP), and open-loop detection. It is available in small TSOT23-5 and SOIC-8 packages.
