RP515K
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 ponents and space by bining 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
