Introduction

AI Translation

The UTC UC2844/2845 are high performance fixed frequency current mode controllers that specifically designed for Off-Line and DC to DC converter applications with minimal external parts count. The differences between UC2844 and UC2845 are the under-voltage lockout thresholds. The UC2844 ideally suited to off-line applications with UVLO thresholds of 16V(ON) and 10V(OFF), and UC2845 has UVLO thresholds of 8.4V(ON) and 7.6V(OFF) for lower voltage applications.

Features

  • Operation output switching frequency up to 500 kHz
  • Automatic feed forward compensation
  • Latching PWM for cycle-by-cycle current limiting
  • High current totem pole output
  • Internally trimmed reference with under voltage lockout
  • UVLO with hysteresis
  • Low startup and operating current
