Overview
| Topology | Buck Converter |
| Input voltage | 5.5-26 V |
| Switching frequency | 200-3000 kHz |
| Output 1 | 3 A |
| IC revision | A |
Description
The TPS25850Q1EVM-088 is an evaluation module (EVM) for TI's TPS25850-Q1 USB Type-C™ and BC1.2 dual type-C ports which is capable of providing up to 6.6-A output current, 3 A for each port with cable compensation. The EVM operates over a range from 5.5 V to 26 V and withstands 40-V transient voltage. The value of cable compensation, current limit, output voltage and switching frequency can be adjusted by resistors on the EVM.
Features
- 5.5-V to 26-V input range, 3-A continuous output current buck converter for each port
- 200-mA capability for OUT pin, 200-mA capability for VCONN power meeting for USB3.1 power requirement
- Forced PWM operation with Spread-Spectrum Dithering at 200 kHz –2.4 MHz
- Fully AEC-Q100 qualified
- Programmable output short current limit: ±15% accuracy overtemperature
- Smart thermal management
- USB battery charging specification Rev. 1.2 DCP mode, divider3 mode, Samsung 1.2 V mode, and USB Type-C Rev. 1.3 compliant
- User-programmable VBUS current limit and internal VCONN current limiting
Typical applications
- USB media hubs, USB charging ports, aftermarket Dual USB chargers
