RP605 SeriesNEW

0.3µA IQ Low Quiescent Current 300mA Buck-Boost DC/DC Converter with Battery Monitor

  • Consumer
  • RoHS

RP605 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.

  • 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
