Nisshinbo Micro Device Inc. RP604
Ultra-low Quiescent Current (IQ = 0.3 μA), 300 mA, Buck-Boost DC/DC Converter
Overview
| Topology | Buck Converter |
| Input voltage | 1.8-5.5 V |
| Output 1 | 5.2 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
- Low-power Wireless Communication Equipment: Bluetooth® Low Energy, ZigBee, WiSunm, ANT
- Wearable Appliances: SmartWatch, SmartBand, Healthcare / Low-power Devices for CPU, Memory, Sensor Device, Energy Harvesting
- Li-ion/Coin Battery-used Equipment
