1.5A 18V 1.4MHz non-Synchronous Step-Down Converter

Overview

TopologyBuck Converter
Input voltage4.5-18 V
Output 13.3 V / 1.5 A
IC revision1.0.0

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
