Fonctionnalités et applications
The UC3844BD1013TR is a high performance current mode PWM controller.
This device 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 a trimmed oscillator for precise DUTY CYCLE CONTROL 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 offstate.
Features:
- Trimmed oscillator for precise fre-quency control
- Oscillator frequency guaranteed at 250khz
- Current mode operation to 500khz
- Automatic feed forward compensation
- Latching pwm for cycle-by-cycle current limiting
- Internally trimmed reference with undervoltage lockout
- High current totem pole output
- Undervoltage lockout with hysteresis
- Low start-up and operating current
