Product Introduction

Overview

The ADP2370ACPZ-R2, produced by Analog Devices Inc., is a high-efficiency, low quiescent current buck (step-down) DC-to-DC converter. This device is designed to provide a compact and efficient power management solution, particularly suited for portable and battery-powered applications. It is available in a small 8-lead, 3 mm x 3 mm LFCSP (QFN) package, making it ideal for space-constrained designs.

Key Features

  • High efficiency with >90% efficiency
  • Low quiescent current of < 14 µA in power saving mode (PSM)
  • Force PWM mode (FPWM) for noise considerations
  • Power-good output to indicate when the output voltage is below 92% of its nominal value
  • Quick output discharge (QOD) function in ADP2371 model
  • Internal power switch and synchronous rectifier for minimal external part count
  • Internal soft start and internal compensation for ease of use
  • Undervoltage lockout to prevent deep battery discharge
  • Soft start to prevent input overcurrent at startup
  • Short-circuit protection and thermal overload protection circuits

Applications

  • Portable and battery-powered equipment
  • Automatic meter readers (WSN)
  • Point of sales and transaction processing instruments
  • Medical instruments
  • Medium format display tablets and pads
