RICOH Electronic Devices Co., Ltd. RP604

Ultra-low Quiescent Current (IQ = 0.3 μA), 300 mA, Buck-Boost DC/DC Converter

Overview

TopologyBuck Converter
Input voltage1.8-5.5 V
Output 15.2 V / 0.3 A

Description

The RP604x is a buck-boost converter featuring a minimum supply current and a high efficiency at low-load. The device operates at the low operating quiescent current(IQ= 0.3 μA) to make the most of battery life for the battery driver operated intermittently.

Features

  • Input Voltage: 1.8 V to 5.5 V
  • Output Voltage: 1.6 V to 5.2 V, 0.1 V step
  • Output Voltage Accuracy: ±1.5%
  • Maximum Output Current: 300 mA at Buck
  • Built-in Driver On-resistance (RP604Z, VIN = 3.6 V): PMOS = Typ.0.12 Ω, NMOS = Typ. 0.12 Ω
  • Operating Quiescent Current (IQ): 0.3 μA
  • Standby Current: 0.01 μA
  • Protection Features: UVLO, OVP, LX Peak Current, and Thermal Shutdown

Typical applications

  • Li-ion/Coin Battery-used Equipment
  • Wearable Appliances: SmartWatch, SmartBand, Healthcare / Low-power Devices for CPU, Memory, Sensor Device, Energy Harvesting
  • Low-power Wireless Communication Equipment: Bluetooth® Low Energy, ZigBee, WiSunm, ANT
