Texas Instruments LM74680EVM Evaluation Module
Texas Instruments LM74680EVM Evaluation Module is configured to evaluate the operation of the LM74680 ideal diode bridge controller in a 12-pin DRR package. The LM74680 enables lower voltage drop and reduced power dissipation to simplify the power supply design, eliminate heat sinks, and reduce PCB area.
The TI LM74680EVM evaluation module demonstrates how an N-channel power MOSFET driven by LM74680 can emulate a very low forward voltage diode and increase efficiency by a prominent factor in bridge rectifiers.
Features
- Reverse current blocking feature required for AC rectification
- Input reverse battery protection
- Drives external N-channel MOSFETs in bridge configuration
- Output LED for output high indication
Applications
- Video doorbells
- IP cameras
- Power distribution systems (24VAC)
