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.
KEY SPECIFICATIONS TYPICAL PERFORMANCE CHARACTERISTICS
• RP517x051x, Ta=25°C
Output current: 300 mA • Output Voltage Range: 0.3 V to 1.2 V (Settable in 0.1 V step) • Output Voltage Accuracy: ±18 mV • Built-in Driver On-resistance (VIN = 3.6 V): Typ. PMOS 0.15 Ω, NMOS 0.15 Ω (RP517Z) • Standby Current: 0.01 µA
