Product Model: LP3669B
LP3669B is a high-performance, isolated adapter and charger with a self-powered primary-side feedback control chip. It achieves constant current and constant voltage functions by detecting the current and voltage on the primary side of the transformer. It has built-in loop stability compensation, eliminating the need for a TL431, optocoupler, and auxiliary winding power supply. LP3669 achieves constant current output by setting the external current limiting resistor and the primary-to-secondary turns ratio of the transformer; constant voltage is achieved by setting the FB voltage divider resistor. To achieve a better output voltage regulation rate, LP3669 has a built-in output cable compensation function, and the output cable compensation value can be adjusted by setting the resistor value on FB. LP3669 integrates multiple protection functions, including VCC clamping/undervoltage protection, output short-circuit protection, and overtemperature protection. LP3669 is packaged in SOP7L.
