NV9701 Overview
Description
NV9701 is a secondary-side synchronous rectifier (SR) controller for isolated flyback converters. By implementing proprietary turn-off control algorithm, NV9701 can reliably support discontinuous conduction mode (DCM), quasiresonant (QR) and continuous conduction mode (CCM) operation, which will help to design robust flyback converters.
Key Features
- Compatibility of continuous conduction mode (CCM), quasi-resonant (QR) and discontinuous conduction mode (DCM) at low side applications
- Wide input voltage ranges up to 26.5V
- Optimized SR gate turn-off threshold control
- Proprietary CCM SR turn-off control algorithm
- Minimized SR turn-on/off propagation delay
- SR MOSFET gate passive clamp
- Low power saving mode
- Small footprint with SOT-23-6L package Topologies / Applications
- USB PD quick chargers for smart phones, feature phones and tablet PCs
- Power adaptor for portable device
