Texas Instruments TPS2561A-Q1 | Demoboard TIDA-01388
CISPR 25 Class 5 Rated Dual Automotive USB Charger Reference Design With Full Front End Protection
Overview
| Topology | Buck Converter |
| IC revision | E1 |
Description
TIDA-01388 is a 21 W dual automotive USB charger solution featuring complete front end protection with small size. The system can clamp fast high-voltage electrical transients and maintain operation through these events. It can also properly respond to a reverse battery polarity event and shut down appropriately.The design accepts a wide input voltage range of 5.5 V to 36 V and regulates two outputs of 5 V@2.1 A for dual USB ports. EMI filtering circuitry is included and the design is compliant with CISPR 25 Class 5 conducted EMI standards.
Features
- Wide Vin front end power supply for dual USB charger systems
- Off-battery operation with reverse battery protection
- Positive and negative transient voltage protection
- Meet CISPR 25 Class 5 conducted EMI standards
- Uses all AEC-Q100 qualified devices
- Small solution size
Typical applications
- Automotive USB Charge
- Electric Toothbrush / Electronic Thermometers
