RP515x Series
Ultra-low Power Consumption 300 mA Buck DC/DC Converter with Battery Monitor
OVERVIEW
No.EA-505-190328
The RP515x is a buck DC/DC converter with a Battery Monitor (BM) featuring ultra-low current and lowvoltage resistance. The battery monitor divides the input voltage (VIN) into 1/3 or 1/4, and directly provides the MCU’s built-in low voltage AD converter with buffered voltage without external circuits.
KEY BENEFITS
● 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.
