Universal Input, Non-Isolated Off-line Regulator Evaluation Board for SOIC8 package
View distributor pricing and availability
The EV174-S-00A Evaluation Board is designed to demonstrate the capabilities of MP174. The MP174 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 EV174-S-00A Evaluation Board is designed as Buck application. EV174-S-00A typically drives a 3.6W with a 12V/300mA load from 85VAC to 265VAC, at 60/50Hz.
The EV174-S-00A has an excellent efficiency and meets IEC61000-4-5 surge immunity and EN55022 conducted EMI requirements. MP174 features various protections, including thermal shutdown (TSD), VCC under-voltage lockout (UVLO), over-load protection (OLP), short- circuit protection (SCP), and open loop protection.
MP174GS is available in SOIC8 package

700V Non-Isolated Regulator up to 400mA Output Current
MP174 is a primary-side regulator that provides accurate constant voltage (CV) regulation without 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 off-line low power applications, such as home appliances and standby power. MP174 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. MP174 features various protections, including thermal shutdown (OTP), VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open loop protection. MP174 is available in small TSOT23-5 package and SOIC8 package.
