Introduction

AI Translation

The UTC UC3842B/3843B 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 UC3842B and UC3843B are the under-voltage lockout thresholds. The UC3842B ideally suited to off-line applications with UVLO thresholds of 16 V (ON) and 10 V (OFF), and UC3843B has UVLO thresholds of 8.4 V (ON) and 7.6 V (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
