Applications
The ST1CC40PUR is suited for step-down power conversion in industrial automation, point-of-load regulation for microcontrollers, and battery-powered portable devices where a wide 3 V to 18 V input range is required. Its high efficiency and small package make it a good fit for IoT sensor nodes, wearables, and embedded systems needing tight output voltage regulation from variable input sources. The tape-and-reel (UR suffix) packaging facilitates high-volume SMT pick-and-place production.

Frequently Asked Questions
What is the input voltage range of ST1CC40PUR and what rail voltages does it support?
ST1CC40PUR accepts input voltages from 3 V to 18 V, covering standard 5 V USB rails, 12 V adapter outputs, and unregulated battery voltages. This wide range allows a single regulator design to work across multiple power architectures without component changes.
How efficient is the ST1CC40PUR and what enables that efficiency level?
The ST1CC40PUR achieves up to 92% conversion efficiency thanks to its integrated synchronous rectifier MOSFET, which replaces a traditional Schottky diode and reduces conduction losses. At 12 V input and moderate load currents, this efficiency significantly lowers power dissipation and temperature rise compared to non-synchronous buck converters.
How small is the ST1CC40PUR package, and does it fit compact IoT node layouts?
The VFQFPN-8 package measures 2 mm × 2 mm with an exposed pad, occupying only 4 mm² of PCB footprint. This is compact enough for single-layer or two-layer boards in IoT sensor nodes and wearables where total component height must remain below 1 mm.
What protection features are integrated in the ST1CC40PUR to improve system reliability?
ST1CC40PUR incorporates overcurrent protection, thermal shutdown (typically at 150°C junction temperature), and soft-start to limit inrush current during power-up. These built-in protections reduce external component count and protect downstream circuits from overvoltage and short-circuit events.
When would ST1CC40PUR be a suitable alternative to a discrete inductor-based buck solution?
ST1CC40PUR is preferable when PCB area is limited to under 10 mm² and the design requires a maximum 18 V input with current-mode control for fast transient response. It eliminates the need for a separate gate driver and external diode, cutting the BOM by at least 3 components versus a discrete solution.
