Product Coverage
PWM Controller
Implements the flyback topology to meet the demands of switching-mode power supply for high-efficiency power systems.
SR Controller
Synchronous rectifier controller for implementing a near-ideal diode emulation to replace Schottky diodes in high-efficiency flyback converters
PD Controller
- Handles USB PD messaging handshake
- Selects voltage from the flyback power supply
- Controls the FET switch on VBUS.
VBUS FET
FET is required to prevent high voltage on VBUS until the right time.
- Only one FET required by USB Type-C for adaptors with captive cable.
- All Adaptors must be able to drive VBUS to 0V when nothing is attached.
AKC6200
Synchronous Rectification Controller
The AKC6200 is a low drop, high-performance synchronous rectification (SR) controller which is designed for the control of synchronous rectification MOSFET in Flyback converter. With built-in power management technology, the AKC6200 can be powered through VD and VIN without any auxiliary winding connected to VDD.
The AKC6200 can support DCM, CCM and quasi-resonant operations and wide output range in PD application. (from 3.3V to 20V for PD3.0 and PPS standard) The built-in intelligent gate regulation control can suppress the voltage spike on SR MOSFET to improve the efficiency performance during operation.
Furthermore, the light operation current at light load condition, the power dissipation is extremely low that the system is compatible with Energy star standard.
