Overview
RP605x Series 300mA Ultra-low Power Buck Boost DC/DC Converter with Battery Monitor No.
EA-516-200226 OVERVIEW RP605x 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.
KEY BENEFITS ● 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.
