Features and Applications

The UC2844BN is of control ICs 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 A.

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 frequency Control
  • Oscillator Frequency Guaranteed at 250 Hz
  • Current Mode Operation to 500 kHz
  • Automatic Feed Forward Copensation
  • Latching PWM for Cycle-by-cycle Current Limiting
  • Internally Trimmed Reference with Undervoltage lockout
  • High Current totem pole output Undervoltage Lockout With Hystersis
  • Low Start-up and Operating Current
