Bright Power isolated power supply PSR S7141S

S7141S is a highly integrated constant current and constant voltage primary-side feedback controller. It integrates high-voltage starting devices and uses self-power supply technology, so that the system does not require starting resistors and power supply diodes. At the same time, the chip has a built-in fixed peak current detection circuit, eliminating the need for a CS resistor; and a built-in FB down-bias resistor, which greatly reduces production costs. Suitable for various low-power AC/DC charger and adapter applications.
