The high efficiency TPSM82843x step-down converter family supports an ultra-low IQ (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 predefined output voltages per part number with 1% accuracy selected through a standard E48 (2%) or E96 (1%) resistor on the VSET pin support a large variety of applications.
