Product Overview

The TEL 2-1211 is an ultracompact isolated 2W DC/DC converter module in a DIP-16 plastic package, occupying only 3.25cm² of PCB space and requiring no external components for full power conversion. It supports a wide 9-18VDC input range (12VDC nominal) with 5VDC/400mA regulated output and 1500V input-output isolation, ideal for cost-sensitive industrial and consumer electronics applications with space constraints.

Key Features

• Ultracompact DIP-16 Package: Tiny footprint of 3.25cm² optimizes high-density PCB layouts.
• 2:1 Wide Input Range: Accepts 9-18VDC input, compatible with diverse power sources to reduce front-end adaptation needs.
• 1500V Electrical Isolation: Provides 1500V DC isolation between input and output, protecting downstream circuits from common-mode noise and surges.
• Low Ripple & Noise: Ensures ≤50mVp-p ripple noise within 20MHz bandwidth for clean power supply to sensitive devices.
• Indefinite Short-Circuit Protection: Offers automatic recovery from continuous short circuits without manual intervention, enhancing system safety.
