CS6552F 数据手册 ( 数据表 ) - HUAJING MICROELECTRONICS

Overview
   CS6552/CS6552F is an offline low-power AC/DC switching power supply with high-precision primary feedback LED constant current drive circuit. It integrates a 600V high-voltage power tube and is suitable for 85Vac~265Vac full-range input and flyback isolation LED constant current drive. Through primary side control, high-precision LED constant current output can be achieved without secondary feedback loops such as optocouplers, reducing costs.

Its features are as follows:
● Primary-side control achieves constant current, without the need for secondary feedback loops such as optocouplers
● Internally integrated 600V high-voltage power MOSFET
● High-precision LED output current within a wide voltage range of 85Vac~265Vac
● Low static power consumption
● Inductor current discontinuous mode
● Built-in leading edge blanking circuit (LEB)
● Output short circuit/open circuit protection
● Current sampling resistor open circuit protection
● Cycle-by-cycle primary inductor current limit
● Power supply overvoltage/undervoltage protection
● Overtemperature protection
● Package form: DIP8
