UCC2750 - Source Ringer Controller

General Description

The UCC3750 Source Ringer Controller provides a complete control and drive solution for a four quadrant flyback-based ring generator circuit.

The IC controls a primary side switch, which is modulated when power transfer is taking place from input to output.

Key Features

  • Provides Control for Flyback Based Four Quadrant Amplifier Topology.
  • Onboard Sine Wave Reference with Low THD.
  • Selectable Ringing Frequency for Different Phone Systems (20Hz, 25Hz and 50Hz).
  • Programmable Output Amplitude and DC Offset.
  • DC Current Limiting for Short Circuit Protection.
  • Secondary Side Voltage Mode Control.
  • Operates from a Single 5V Supply.
