Introduction
The UC2842B provides the necessary features to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count. Internally implemented circuits include under-voltage lockout featuring start up current less than 0.5 mA, a precision reference trimmed for accuracy at the error amp input, logic to insure latched operation, a PWM comparator which also provides current limit control, and a totem pole output stage designed to source or sink high peak current. The output stage, suitable for driving N channel MOSFETs, is low in the off state.
Features
- Optimized for off-line and DC to DC converts
- Low start up current (<0.5 mA)
- Automatic feed forward compensation
- Pulse-by-Pulse current limiting
- Enhanced load response characteristics
- Under-voltage lockout with hysteresis
- Double pulse Suppression
- High current totem pole output
- Internally trimmed bandgap reference
- 500kHz operation
Applications
- Power converter
