Introduction
The
to 5.5 V input, with a 1.6 to 3.3 V dynamically adjustable output voltage.
nano-quiescent miniaturized synchronous step-down converter, which implements
enhanced peak current control (PCC) and advanced design circuitry to minimize quiescent current. The device embeds a
controlled load switch to supply a subsystem with VIN_AUX voltage rail.
The
demonstrates how highly efficient conversion can be achieved thanks to the
TQFN12 package of 2.0x1.7 mm), a 2.2 μH inductor, and two small capacitors.
The
key application benefits include high efficiency, and small PCB size and thickness. It is extremely suitable
for power conversion solutions in wearable applications and fitness accessories, personal tracking monitoring, smart watches,
sport bands, energy harvesting, wireless sensors, industrial sensors, portable low-power devices, single cell Li-ion battery
applications, as well as Bluetooth
®
low energy and Zigbee applications.
