The UC3842BN is a high-performance current mode PWM Controller IC that 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 a start-up current less than 0.5mA, a precision reference trimmed for accuracy at the error amp input, logic to ensure latched operation, a PWM comparator that also provides current limit control and a totem pole output stage designed to source or sink high peak current.
Features:
- Trimmed oscillator for precise frequency control
- Automatic feed-forward compensation
- Latching PWM for cycle-by-cycle current limiting
- Internally trimmed reference with under-voltage lockout
- High current totem pole output
- Under voltage lockout with hysteresis
- Low start-up and operating current
