UCC3750 Datasheet Source Ringer Controller

Manufacturer: Unitrode

Overview: Source Ringer Controller application INFO available UCC2750 UCC3750.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.

It also controls two secondary switches which act as synchronous rectifier switches during positive power flow.

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.
