UC3863A Datasheet Low Cost Power-saving Mode Pwm Controller

Manufacturer: Unisonic Technologies

Overview: UNISONIC TECHNOLOGIES CO., LTD UC3863A LINEAR INTEGRATED CIRCUIT LOW COST POWER-SAVING MODE PWM CONTROLLER FOR FLYBACK CONVERTERS.

General Description

The UC3863A is a high performance current mode PWM controller ideally suited for low standby power.

The PWM switching frequency is programmable externally at normal operation.

Low VDD startup current make the power reliable on startup design and a large value resistor could be used in the startup circuit to minimize the standby power.

Key Features

  • S.
  • 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.
  • OLP with automatic recovery.
  • OTP and OVP with automatic recovery.
  • VDD clamp for higher security.
  • Programmable PWM Frequency.
  • Gate output voltage clamped at 16V.
  • Low start-up current.
  • Cycle-by-cycle Current.
