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 5.5 V
