About RICOH Electronic Devices
RP515 Series
Low Power Consumption 300mA Buck DC/DC Converter with Battery Monitor
- RoHS
Product Specifications
The RP515 is a buck DC/DC converter with a Battery Monitor (BM) featuring ultra-low current and low-voltage resistance. The battery monitor divides the input voltage (VIN) into 1/3 or 1/4 to a buffer output and inputs a signal directly into the MCU’s built-in low voltage AD converter without external circuits. It is suitable for use in wearable and IoT devices that require miniaturization and long-lifetime of battery.
- Ultra-low consumption current (IQ: 0.3 µA) with the VFM control for DC/DC (switching frequency: 1 MHz max.)
- High efficiency under light load conditions
- Reducing components and 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

1.0 V (10) / 1.2 V (12) / 1.5 V (15) / 1.8 V (18) / 2.4 V (24) / 2.5 V (25) / 2.8 V (28) / 3.0 V (30) / 3.1 V (31) / 3.3 V (33) / 3.6 V (36) / 4.0 V (40) - # … Select the division ratio of BM output voltage.
3: VIN /3
4: VIN /4 - $ … Select the auto-discharge option for DC/DC.
A: DC/DC auto-discharge is not included
B: DC/DC auto-discharge is included
* Auto-discharge function quickly lowers the output voltage to 0 V, when the chip enable signal is switched from the active mode to the standby mode, by releasing the electrical charge accumulated in the external capacitor.
