CR5201
CR5201 is a high performance offline PWM controller used in small power AC / DC charger and power adapter. The chip uses the topology of the original edge detection and adjustment, and therefore the application without the TL431 and optocoupler. Chip built-in constant current / constant voltage two control modes.
Constant current control, the maximum output current and output power can be set through limiting resistor RS CS pin. When the constant voltage control, a built-in constant voltage sampling circuit, and the precision error of the reference voltage of the comparator to ensure high performance and high precision of the chip. In addition, the built-in line loss compensation circuit to ensure the accuracy of the output voltage curve from no load to full load conditions. The chip also has a very low quiescent operating current (typically 300u) in an idle state, CR5201 work in PFM mode, the minimum operating frequency up to 100Hz, so low standby power consumption of the chip (to meet the low standby power consumption at 30mW).

CR5201 designed for a variety of fault protection measures, including cycle-by-cycle current limiting, peak current limit, overvoltage protection, FB open circuit protection, short circuit protection, LEB, power clamp and undervoltage lockout feature.
