3 Description
The high efficiency TPSM82843x step-down converter
family supports an ultra-low typical operating
quiescent current of 275nA and a typical shutdown
current of only 4nA. The inductor is integrated into the
QFN package improving ease of use and reducing
the bill of material down to only three passive
components.
The RF-friendly device uses DCS-Control for a low
output voltage ripple. The device is designed to
power wireless applications like Wi-Fi or Bluetooth.
The device switches at 1.5MHz and has high
efficiency even at light load current down to 10μA
for long battery life and easy thermal management.
Humidity, temperature or vibration have no influence
on the output voltage accuracy due to the integrated
feedback divider. Therefore, the device is also
an excellent choice for industrial point of load
applications.
18 pre-defined output voltages per part number with
1% accuracy selected through a 1% resistor on the
VSET pin support a large variety of applications.
