MaxLinear XRP7665 | Demoboard XRP76XXEVB
2A/3A 18V Synchronous Step-Down Regulator, Constant frequency (XRP7664-65), Light-Load efficiency (XRP7674-75)
Overview
| Topology | Buck Converter |
| Input voltage | 4.5-18 V |
| Output 1 | 3.3 V / 2 A |
| Output 2 | 3.3 V / 3 A |
| IC revision | 2.0.0 |
Description
The EXAR XRP76XX Evaluation kit is a fullyassembled and tested surface-mount PCB thatdemonstrates the XRP7664, XRP7665,XRP7674 and XRP7675 synchronous buckregulators. The current-mode switchingregulator generates a preset 3.3V output witha load of up to 2A (XRP7664, XRP7674) and3A (XRP7665, XRP7675).The EVB kit requires a single input voltage VIN source if EN is tied to VIN via jumper J1 (default setting as supplied from EXAR). If J1 is set to EN=EXT position then a logic-levelsignal is required at EN pin in order to turn theregulator on and off.
Features
- 2A/3A Continuous Output Current
- 4.5V to 18V Wide Input Voltage
- PWM Current-Mode Control
- Adjustable Output Voltage
- 2% Accuracy
- Programmable Soft-Start and EnableFunction
- Constant frequency (XRP7664-65)
- Light-load efficiency (XRP7674-75)
- Built-in Thermal, Over Current, UVLOand Output Over-Voltage Protections
- RoHS Compliant “Green”/Halogen Free8-Pin Exposed Pad SOIC Package
