Overview
| Topology | Buck Converter |
| Input voltage | 4.5-18 V |
| Output 1 | 3.3 V / 1.5 A |
| IC revision | 1.0.0 |
Description
The EXAR XRP7659 Evaluation kit is a fully assembled and tested surface-mount PCB that demonstrates the XRP7659 non-synchronous step-down regulator. The current-mode switching regulator generates a preset 3.3V output with a load of up to 1.5A. The EVB kit requires a single input voltage VIN source, if EN is tied to VIN via jumper J1
Features
- 1.5A Continuous Output Current
- 4.5V to 18V Widw Input Voltage
- PWM Current-Mode Control
- 1.4Mhz Constant frequency
- Adjustable Output Voltage
- 0,81V to 15V Range / =+ or - 3% Accuracy
- Enable Function and integrated Softstart
- Built-in Thermal, Over-Current, UVLO and output Over-Voltage Protection
- RoHS Compliant, "Green"/Halogen Free SOT-23-6 Package
