RP517x Series
0.3 V Ultra-low Output Voltage 300 mA Buck DC/DC Converter
No.EA-519-190325
OVERVIEW
RP517x 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 3 packages: WLCSP, DFN and SOT. Suitable for IC cards due to WLCSP's thickness of 0.4 mm and
less.
