LD5516C

LD5516C 08/10/2016 Primary-Side Quasi-Resonant Controller, REV. 00 Operating in CV/CC Mode General Description The LD5516C is a primary-side Quasi-Resonant feedback controller capable to operate in CV/CC mode for small power AC/DC charger and adapter, a superior solution for Pump Express Plus™ based application. It minimizes the components counts and is available in a tiny SOT-26 package. Those make it an ideal design for low cost and high performance applications. The LD5516C provides fixed constant current operation to boost more power. Both of them are programmable constant voltage, requiring neither photo-coupler nor secondary-side control circuit. Also, the LD5516C feature feedback loop open protection, internal OTP (Over Temperature Protection), wide-range and different output voltage level OVP (Over Voltage Protection)… etc., to prevent the circuit from being damaged under abnormal conditions.
