Introduction

AI Translation

The UCx84xA family of control devices is a pin-for-pin compatible improved version of the UCx84x family. Providing the necessary features to control current - mode or switched - mode power supplies, this family of devices has many improved features: startup current is less than 0.5 mA, oscillator discharge is trimmed to 8.3 mA, and during UVLO, the output stage can sink at least 10 mA at less than 1.2 V for VCC over 5 V.

Features

AI Translation
  • Optimized for Off - Line and DC - DC Converters
  • Low Start - Up Current (<0.5 mA)
  • Trimmed Oscillator Discharge Current
  • Automatic Feedforward Compensation
  • Pulse - by - Pulse Current Limiting
  • Enhanced Load Response Characteristics
  • Undervoltage Lockout With Hysteresis
  • Double Pulse Suppression
  • High - Current Totem Pole Output
  • Internally - Trimmed Bandgap Reference
  • Up to 500 - kHz Operation
  • Create a Custom Design Using the UCx84xA With the WEBENCH Power Designer

Applications
