Part Number: LE75181

Function: Ringing Access Switch / VE750 Series

Package: SOIC 16 Pin Type

Manufacturer: Zarlink Semicoductor

Pinouts:

Description

The VoiceEdge™ family VE750 series of Line Card Access Switches (LCAS) is a family of monolithic solid-state switches that is designed to provide both power ringing access and test access on the analog line card. These devices, while not a pin for-pin replacement for the traditional electromechanical relay (EMR) solution, provide the equivalent switching functionality. The VE750 series LCAS is meant as a solid-state alternative to the EMRs.

Features

1. Small size/surface-mount packaging
2. Monolithic IC reliability
3. Low impulse noise
4. Make-before-break, break-before-make operation
5. Clean, bounce-free switching
6. Low, matched ON-resistance
7. Built-in current limiting, thermal shutdown, and SLIC protection
8. 5 V only operation, very low power consumption

Part Number: UCC28910

Function: High-Voltage Flyback Switcher

Package: SOIC-7 Pin Type

Manufacturer: Texas Instruments

Pinouts:

 

Description

The UCC28910 is dedicated to isolated flyback power supplies and provides output voltage and current regulation without the use of an optical coupler. The device incorporates a 700-V power FET and a controller that processes operating information from the auxiliary flyback winding and from the power FET to provide precise output voltage and current control.

Features

1. Constant-Voltage (CV) and Constant-Current (CC) Output Regulation Without Optical-Coupler

2. ±5% Output Voltage Regulation Accuracy

3. ±5% Output Current Regulation With AC Line and Primary Inductance Tolerance
Compensation

4. Valley Switching and Frequency Dithering to Ease EMI Compliance
