Product Description

MP174是一款原边控制调节器,可以在无光耦合器的条件下提供精确的恒定电压(CV)调节。MP174支持降压、升降压、升压和反激拓扑。它内部集成了700V MOSFET,可简化结构,节约成本,是离线低功率应用的理想之选,如家用电器和备用电源。MP174是一款绿色节能型调节器。随着负载的减少,它的峰值电流和开关频率均会随之降低。这种特性使其在轻载时能达到极高的效率,有效地提升了芯片的整体平均效率。MP174具备多种保护功能,包括热保护(OTP)、VCC欠压锁定保护(UVLO)、过载保护(OLP)、短路保护(SCP)和开环保护。MP174有小体积的TSOT23-5封装和SOIC-8封装可选。

Kit details

The EV174-J-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-J-00A Evaluation Board is designed as Buck application. EV174-J-00A typically drives a 3.6W with a 12V/300mA load from 85VAC to 265VAC, at 60/50Hz.

The EV174-J-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.

MP174GJ is available in TSOT23-5 package.
