Texas Instruments TPS25850-Q1
Small size, rated 30-W automotive dual USB Type-C® charger reference design
Overview
| Topology | Buck Converter |
| Input voltage | 6-26 V |
| Output 1 | 5.17 V / 3 A |
| IC revision | 001 |
Description
This reference design is a small size design (40 mm × 40 mm) for automotive USB Type-C® charger with dual 15-W output. The TPS25850-Q1 is used as DC/DC regulator and port controller, The efficiency of solution is 92.37% at dual 15-W output. Programmable cable droop compensation helps portable devices charge at optimum current and voltage under heavy loads. And a negative temperature coefficient (NTC) thermistor is implemented for intelligent thermal management to reprogram the output voltage in over-temperature condition.
Features
- Small size design
- 92.37% peak efficiency at full load
- Dual USB Type-C® charger
- Thermal management function
- Programmable cable droop compensation
Typical applications
- Aftermarket head unit
