PFS7633H

HiperPFS - 4 devices will be a continuous conduction mode (CCM) boost PFC controller, grid drive and 600 V power MOSFET integrated in a (internal earthing pin connected) thin power package.HiperPFS - 4 device eliminates external current sense resistor, so as to avoid the relevant power loss.Its innovative control technology, can be in the output load, the input voltage and input power frequency cycle adjustment switch frequency.

This control technique can improve the efficiency of the whole load range, especially under the condition of light load efficiency.In addition, due to its wide bandwidth spectrum distribution effect, can reduce the requirement of EMI filter.HiperPFS - 4采用先进的数字技术来实现输入电压监测、输入电压前馈调节和功率因数改善，同时核心控制器采用模拟技术来维持极低的空载功耗。

HiperPFS - 4 also has an integrated nonlinear error amplifier, and can improve the dynamic responses of the load.The power of the user in addition to set ready (PG) signal, also can choose power limit function.HiperPFS - 4具备Power Integrations的整套标准保护功能，例如欠压保护、过压保护、电压缓升/跌落保护和迟滞热关断等。此外，HiperPFS-4还提供功率MOSFET逐周期限流和安全工作区(SOA)保护、限制输出功率的过载保护以及引脚到引脚短路保护。
