描述 Description

Primary-Side Quasi-Resonant Controller,Operating in CV/CC Mode
The LD5718AC is a primary-side Quasi-Resonant controller capable of operating in CV/CC mode for small to medium power AC/DC charger and adapter. When paired with LD8108A, the LD5718AC will support speedy charger design for MediaTek Pump Express Plus™ based and Qualcomm® Quick Charge™ 2.0 based protocol. Using Leadtrend Speedy Charge™ technology, it will be easy to minimize the component counts. 
The LD5718AC can be programmed constant voltage output which only require single photo-coupler by LD8108. Also, the LD5718AC features external/internal OTP (Over Temperature Protection), wide-range and output voltage level OVP (Over Voltage Protection)… etc., to prevent the circuit from being damaged under abnormal conditions.
The LD5718AC is available in a SOP8 package.
