Frequently Asked Questions
What is the input voltage range of the TPS610981DSET?
The TPS610981DSET accepts input voltages from 0.7V minimum to 4.5V maximum with a 1.5V nominal, allowing it to operate from single alkaline, NiMH, or deeply discharged Li-ion cells, maximizing usable battery capacity in portable and IoT devices.
What output voltage does the TPS610981DSET provide?
The TPS610981DSET delivers a fixed 3.3V output voltage via a synchronous boost converter with an integrated LDO post-regulator, providing a stable and low-noise supply for microcontrollers, wireless modules, and analog circuits from low-voltage battery inputs.
What is the converter topology of the TPS610981DSET?
The TPS610981DSET uses a synchronous boost converter topology with current-mode PWM control combined with an integrated LDO stage, which improves output voltage regulation accuracy and reduces output noise compared to a standalone boost converter.
What package does the TPS610981DSET use and what temperature range does it support?
The TPS610981DSET is housed in a 6-pin WSON (S-PDSO-N6) package and is rated for an operating temperature range of -40°C to 85°C, making it suitable for industrial-grade portable equipment and outdoor IoT deployments in varying environmental conditions.
Is the TPS610981DSET suitable for wireless and RF-powered IoT devices?
Yes, the integrated LDO in the TPS610981DSET provides a low-noise 3.3V output that is well-suited for powering RF transceivers, PLLs, and sensors in Bluetooth, Zigbee, and LoRa IoT nodes, where supply noise can directly degrade wireless communication performance.
