Low Power Consumption 300mA Buck-Boost DC/DC Converter with Battery Monitor
RP605 is an ultra-low power DC/DC converter with a Battery Monitor (BM). The battery monitor divides the input voltage (VIN) into 1/3 or 1/4 and directly provides the buffered voltage to a low-voltage AD converter in MCU, it monitors the remaining quantity of the battery.
- Long-time operation of battery powered equipment and downsizing of battery due to the ultra-low consumption current (IQ = 0.3 µA).
- Reducing components and saving space by combining DC/DC and BM into a single chip.
- Suitable for coin batteries and USB ports due to its wide input voltage range from 1.8 V to 5.5 V
Consumer Input Voltage Range 1.8 V to 5.5 V (6.5 V) Operating Temperature Range -40°C to 85°C (125°C) Standby Current Typ. 0.01 µA Operating Quiescent Current DC/DC Section: Typ. 0.3 µA
BM Section: Typ. 0.1 µA
Output Voltage Range 1.6 V to 5.2 V (0.1 V step) Output Voltage Accuracy ±1.5% (Ta = 25°C) Output Current 300 mA Package WLCSP-20-P3, DFN(PLP)2730-12 BM Output Voltage VIN/3 (RP605xxx3x)
