Description
The UTC UC3842A/3843A provide the necessary functions to implement off-line or DC to DC fixed frequency current mode , controlled switching circuits with a minimal external part count
SOP-8
Features
- Low external part count.
- Low start up current ( Typical 0.12mA ).
- Automatic feed forward compensation.
- Pulse-by-Pulse current limiting.
- Under-voltage lockout with hysteresis.
- Double pulse Suppression.
- High current totem pole output to drive MOSFET directly.
- Internally trimmed band gap reference.
- 500kHz operation
