NXP Semiconductors TEA2208T Full Wave Bridge Rectifier Controller
NXP Semiconductors TEA2208T Full Wave Bridge Rectifier Controller replaces the traditional diode bridge and uses the TEA2208T with low-ohmic high-voltage external MOSFETs. This improves the power converter's efficiency, as the typical rectifier diode-forward conduction losses are eliminated. Efficiency can improve up to about 1.4% at 90VAC mains voltage. NXP Semiconductors TEA2208T Full Wave Bridge Rectifier Controller is designed in a silicon-on-insulator (SOI) process.
Features
- Forward conduction losses of the diode rectifier bridge are eliminated
- Low 2mW IC power consumption
- Integrated high-voltage level shifters
- Directly drives all 4 rectifier MOSFETs
- Low external part count
- Integrated X-capacitor discharge (2mA)
- Self-supplying
- Full-wave drive improving total harmonic distortion (THD)
- S014 package
- Undervoltage lockout (UVLO) for high- and low-side drivers
- Drain-source overvoltage protection for all external power MOSFETs
- Gate pull-down currents at start-up for all external power MOSFETs
Applications
- Adapters
- Power supplies for desktop PCs and all-in-one PCs
