Overview
| Topology | Buck Converter |
| Input voltage | 20-36 V |
| Output 1 | 20 V / 14.3 A |
| IC revision | 1.0 |
Description
The EPC91109 evaluation board features a very compact and efficient 20–36 V to 12/16/20 V, two-phase synchronous buck converter. It uses four EPC2057, a 50 V-rated eGaN® FET, and the LTC7890, an analog two-phase step-down controller. The board can be configured as a two-phase interleaved converter with a single output, or as a dual-output buck converter.As the former, it can deliver up to 14.3 A into a 12 V load from a 36 V supply, equivalent to 180 W of input power, the maximum allowed by the USB-PD 3.1 specification for a 36 V bus. The power stage area, including the inductors, measures 24 x 24 mm; it has a maximum component height of 3 mm; and it does not require a heatsink or forced air for cooling
Features
Configurable to operate in either two-phase or single phase, dual-output modeUtilizes a small inductor of just 6.95 x 6.60 mm and 3 mm thicknessNo heatsink or airflow requiredADI’s LTC7890 100 V two-phase synchronous buck controller for GaN FETs
Typical applications
- Automotive consoles
- Computing, industrial, consumer, and telecom power
