Description
RP512 is a buck DCDC converter featuring 0.3 µA ultra-low operating quiescent current. It is suitable for use in wearable and IoT devices that require miniaturization and long-lifetime of battery.
Key Benefits
- VFM (fSW up to 1 MHz) control achieves 0.3 µA ultra-low operating quiescent current.
- The wide range of VIN from 2.0 V to 5.5 V allows operation from coin cell to USB port.
- Total mount area including CIN, COUT, and inductor is 10.6 mm2.
- Selectable packages including WLCSP, DFN, and SOT. 0.4 mm-thickness WLCSP package adaptable to IC cards.
