Overview

The UC3863 is a high performance current mode PWM controller ideally suited for low standby power. The PWM switching frequency is programmable externally at normal operation.

  • UTC proprietary frequency hopping technology for Improved EMI performance. * Power-saving mode for high light-load and standby efficiency * Dynamic peak current limiting for constant output power * Built-in synchronized slope compensation * OTP,OLP,OVP and VDD clamp for higher security
  • Programmable PWM Frequency * Gate output voltage clamped at 15V * Low start-up current * Cycle-by-cycle Curre
