What are the key features of TPS82740ASIPR?
- 200 mA step-down converter with 2.2 V to 5.5 V input range and adjustable 1.8 V to 2.5 V output, covering lithium-ion and dual-cell battery rails
- Dual-mode PWM/PFM operation maximizes efficiency from light load to 200 mA full load, extending battery run time in IoT and wearable devices
- Ultra-compact 9-ball BGA package occupies minimal board area, enabling high-density power solutions in wireless sensor nodes and portable medical devices
What is TPS82740ASIPR used for?
TPS82740ASIPR suits ultra-low-power wireless sensor nodes, Bluetooth modules, and wearable devices that run from a 1-cell or 2-cell lithium battery and need a stable 1.8 V to 2.5 V rail at up to 200 mA. Its PFM mode keeps quiescent current extremely low during sleep intervals, making it ideal for duty-cycled IoT devices with long battery life requirements. The tiny BGA package also enables dense power management on multi-layer PCBs in smart cards, medical patches, and compact industrial sensors.

Frequently Asked Questions
What input voltage range and output voltage range does TPS82740ASIPR support?
TPS82740ASIPR accepts 2.2 V to 5.5 V at its input, spanning single-cell lithium-ion discharged voltage up to a USB 5 V rail. Its adjustable output covers 1.8 V to 2.5 V at up to 200 mA, accommodating the core and I/O supply voltages for most low-power wireless SoCs and microcontrollers.
How do the PWM and PFM modes of TPS82740ASIPR improve battery life in IoT devices?
In heavy-load conditions TPS82740ASIPR operates in PWM mode for low output ripple, while at light loads it automatically switches to PFM mode, reducing switching losses and quiescent current to microampere levels. This dual-mode behavior can extend battery life in duty-cycled IoT nodes by 30% or more compared to a fixed-frequency PWM regulator running at the same light-load current.
Which battery chemistries are compatible with TPS82740ASIPR as an input source?
TPS82740ASIPR operates down to 2.2 V input, covering a single lithium-ion cell discharging to its 2.5 V cutoff, as well as two alkaline AA cells at 2.4 V nominal. The 5.5 V maximum input also accommodates a fully charged 2-cell NiMH pack at 3.0 V and a standard 5 V USB source, giving designers flexibility across multiple battery chemistries without a second converter.
For a compact PCB design, how small is the TPS82740ASIPR package footprint?
TPS82740ASIPR uses a 9-ball BGA package with a roughly 1.5 mm x 1.5 mm footprint, among the smallest step-down converter packages available for a 200 mA device. This footprint is more than 10 times smaller than a typical SOT-23 or WSON converter solution, enabling power management integration on PCBs as small as 10 mm x 10 mm in wearable or smart card applications.
