LD5718AC - Primary-Side Quasi-Resonant Controller

Key Features

  • 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 LD8.
