Fairchild/ON Semiconductor SG6203DZ
- Part Number:
- SG6203DZ
- Manufacturer:
- Fairchild/ON Semiconductor
- Ventron No:
- 3268367-SG6203DZ
- Description:
- IC SYNCHRONOUS FRWRD CTRLR 8DIP
- ECAD Model:
-
- Datasheet:
- SG6203
Description
The SG6203 is a synchronous rectifier controller designed for flyback converters. It eliminates the need for an additional transformer winding by obtaining the synchronous signal from the primary switch through a single diode. The SG6203 prevents "shoot-through" and "cross conduction" in continuous conduction mode (CCM) and reverse energy flow in discontinuous conduction mode (DCM).
Features
Low operation current (1.7mA)
Single resistor for timing setting
Internal automatic tracking for optimum dead time
No reverse energy flow at light load
Best suited for primary green-mode PWM ICs
Wide supply voltage range (6V to 20V)
Built-in 18V Zener diode
Optional current sensing:
Current shunt
RC network for improved efficiency
Applications
Flyback converters, including:
Power adapters
Open-frame SMPS
