Product Introduction

Overview

The TPS82740ASIPR from Texas Instruments is a fully integrated step-down converter module designed for ultra-low power applications. It features an ultra-low quiescent current consumption of typically 360 nA, making it ideal for battery-powered devices and energy harvesting systems. This module includes all necessary passive components, such as the switching regulator, inductor, and input/output capacitors, integrated into a small 2.3 mm × 2.9 mm MicroSIP™ package. The device operates with an input voltage range from 2.2 V to 5.5 V and supports output currents up to 200 mA.

Q & A

  1. What is the typical quiescent current consumption of the TPS82740ASIPR?

    The typical quiescent current consumption is 360 nA.

  2. What is the input voltage range for the TPS82740ASIPR?

    The input voltage range is from 2.2 V to 5.5 V.

  3. What is the maximum output current supported by the TPS82740ASIPR?

    The maximum output current is up to 200 mA.

  4. How is the output voltage selected for the TPS82740ASIPR?

    The output voltage is selected using three voltage select pins (VSEL1, VSEL2, VSEL3) in 100-mV steps.

  5. What is the DCS-Control™ topology and its benefits?

    DCS-Control™ is an advanced regulation topology that combines the advantages of hysteretic and voltage mode control, offering excellent AC load regulation, low output ripple voltage, and seamless transition between PFM and PWM mode operation.

  6. What is the purpose of the integrated load switch in the TPS82740ASIPR?

    The integrated load switch, controlled by the CTRL pin, distributes the selected output voltage to a temporarily used sub-system and supports soft switching.

  7. How does the TPS82740ASIPR handle output voltage discharge?

    The device features a discharge circuit that connects the VOUT and LOAD pins to GND when disabled, preventing residual charge voltages on connected capacitors.

  8. What are the thermal characteristics of the TPS82740ASIPR?

    The junction-to-ambient thermal resistance (RθJA) is 83 °C/W.

  9. What are some common applications for the TPS82740ASIPR?

    Common applications include Bluetooth® Low Energy, RF4CE, Zigbee, wearable electronics, and energy harvesting systems.

  10. What is the package size of the TPS82740ASIPR?

    The package size is 2.3 mm × 2.9 mm in a MicroSIP™ package.
