TEA1721FT
Overview
The TEA1721 is a small and low cost module Switched Mode Power Supply (SMPS) controller IC for low power applications (up to 5 W) and operates directly from the rectified universal mains input. The device includes a high voltage power switch (700 V) and has been optimized for flyback converter topologies to provide high-efficiency over the entire load range with ultra-low power consumption in the no-load condition.
- Low power SMPS controller with integrated power switch designed for applications up to 5 W
- 700 V high voltage power switch for global mains operation
- Primary sensing for control of the output voltage without optocoupler and secondary feedback circuitry
- Minimizes audible noise in all operation modes
- USB battery charging and
