Description

The RP604 is a buck-boost converter featuring a minimum supply current and a high efficiency at low-load. The device operates at the low operating quiescent current (IQ = 0.3 µA) to make the most of battery life for the battery driver operated intermittently.

Key Benefits

  • The low supply current (IQ = 0.3 μA) can achieve making battery life longer and battery’s size-reduction.
  • Wide range of input voltage (1.8 V to 5.5 V) can support for every batteries from a coin-type battery to a USB port.
  • Selectable package: WLCSP-20-P2 or DFN(PL)2730-12
