The UC2843BD1 is a high-performance current mode PWM Controller IC. It provides the necessary features to implement offline 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. The output stage, suitable for driving N-channel MOSFETs is low in the off-state.


Features:

  1. Trimmed oscillator for precise frequency control
  2. Automatic feed-forward compensation
  3. Latching PWM for cycle-by-cycle current limiting
  4. Internally trimmed reference with under-voltage lockout
  5. High current totem pole output
  6. Under-voltage lockout with hysteresis
  7. Low start-up and operating current
