TEA1530T Overview
Description
The GreenChip II is the second generation of green Switched Mode Power Supply (SMPS) controller ICs. Its high level of integration allows the design of a cost effective power supply with a very low number of external components.
Key Features
- 2.1 Distinctive features I Universal mains supply operation, 70 VAC to 276 VAC
- I High level of integration, resulting in a very low external component count
- I Fixed frequency operation
- 2.2 Green features I Cycle skipping mode at very low loads; input power < 300 mW at no-load operation for a typical adapter application
- I On-chip start-up current source
- 2.3 Protection features I I I I I I I Safe restart mode for system fault conditions
- Undervoltage protection (foldback during overload)
- IC OverTemperature Protection (OTP) (latched)
- Low and adjustable OverCurrent Protection (OCP) trip level
- Mains voltage-dependent operation-enabling level
