Introduction
AI Translation
This series of modular power supplies are three-terminal switching regulators featuring high efficiency, low power dissipation, and minimal heat generation — no heatsink required for stable and reliable operation. They address the drawbacks of conventional three-terminal linear regulators, namely low efficiency and excessive heat, making them an ideal drop-in replacement for three-terminal linear regulators.
Features
AI Translation
- Wide input voltage range: 4.5 - 32VDC
- High conversion efficiency (up to 96%), low no-load current: 0.2mA (typ)
- Pin-compatible with LM78xx series three-terminal linear regulators
- Output short-circuit protection (self-recovering)
- Operating temperature: -40°C ~ +85°C
Applications
AI Translation
- Industrial control system power supplies
- Power monitoring system power supplies
- Instrumentation and measurement power supplies
