Ultra-low Power Consumption 100 mA Buck DC/DC Converter with Battery Monitor

Overview

TopologyBuck Converter
Input voltage1.8-5.5 V
Switching frequency1000 kHz
Output 14 V / 0.1 A

Description

The RP514x is a buck DC/DC converter with a Battery Monitor (BM) featuring ultra-low current and low-voltage resistance.The battery monitor divides the input voltage (VIN) into 1/3 or 1/4, and directly provides the MCU’s built-in low voltage AD converter with buffered voltage without external circuits.

Features

  • Supply Current: Typ. 0.3 μA
  • Output Current: 100 mA
  • Input Voltage Range: 1.8 V to 5.5 V
  • Output Voltage Range : 1.0 V to 4.0 V
  • Output Voltage Accuracy: ±1.5%

Typical applications

  • Coin cell-used equipment and Li-ion battery-used equipment
  • Wearable devices such as SmartWatch, SmartBand and Health monitoring / Low Power CPU, Memory, Sensor device and Energy Harvester
  • Low Power RF Modules such as Bluetooth® LE, Zigbee, WiSun and ANT
