MP156GJ集成电路（IC）的ACDC转换器离线开关规格书PDF中文资料

MP156GJ属于集成电路（IC）的ACDC转换器离线开关。由美国芯源系统有限公司制造生产的MP156GJAC DC 转换器，离线开关该系列是元器件级控制产品，用于构建将交流市电转换为直流电（通常电压大幅降低）的设备。集成和未集成系统主要开关元件的器件均包括在内。由于高输入输出电压比，以及此类系统中通常需要隔离，这些器件通常与外部变压器配合使用。尽管通常使用定制变压器来实现此用途，但也有许多专门用于此用途的库存产品，请参见“开关转换器，SMPS 变压器”标题。

DESCRIPTION

MP156 is a primary-side regulator that provides accurate constant voltage (CV) regulation without opto-coupler, support Buck, Buck-Boost, Boost and Flyback topologies. It has an integrated 500V MOSFET to simplify the structure and reduce costs. These features make it a competitive candidate for off-line low power applications, such as home appliances and standby power.

FEATURES

• Primary-side constant voltage (CV) control, supporting Buck, Buck-Boost, Boost and Flyback topologies

• Integrated 500V/20Ω MOSFET

• <30mW no-load power consumption

• Up to 4W output power

• Maximum DCM output current less than 130mA

• Maximum CCM output current less than 220mA

• Low VCC Operating Current

• Frequency foldback

• Limited maximum frequency

• Peak-current compression

• Internal high-voltage current source

• Internal 350ns leading-edge blanking

• Thermal shutdown (auto restart)

• VCC under voltage lockout with hysteresis

• Timer based over-load protection.

• Short-circuit protection

• Open-loop protection

APPLICATIONS

• Home appliances, white goods and consumer electronics

• Industrial controls

• Standby power
