RP605K
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

xx: Specify the DC/DC set output voltage (VSET)
Fixed output voltage type: 1.6 V (16) to 5.2 V (52) in 0.1 V step
Refer to the Product-specific Electrical Characteristics for detail information
#: Specify the division ratio of BM output
3VIN/3
4VIN/4
$: Specify the DC/DC auto-discharge option.
A: DC/DC auto-discharge is not included
B: DC/DC auto-discharge is included
(1)Auto-discharge function quickly lowers the output voltage to 0 V by releasing the electrical charge accumulated in the
external capacitor when the chip enable signal is switched from the active mode to the standby mode.
