Description
RP517 is a low-voltage resistance buck DC/DC converter featuring ultra-low 0.3 µA quiescent current and 0.3 V output voltage. Suitable for wearable and IoT devices which require long-life batteries and downsizing.
Key Benefits
- Ultra-low consumption current (IQ: 0.3 µA) with the VFM control for DC/DC (switching frequency: 1 MHz max.)
- Suitable for low power devices due to its ultra-low output voltage range from 0.3 V to 1.2 V
- Suitable for coin batteries and USB ports due to its wide input range from 1.8 V to 5.5 V
- Selectable 2 packages: WLCSP and DFN. Suitable for IC cards due to WLCSP’s thickness of 0.4 mm and less.
