Frequently Asked Questions
What converter topology does XPS62823DLCR use and how does that benefit efficiency at light loads?
XPS62823DLCR uses a synchronous step-down (buck) switching topology, which replaces the lower diode with a low-resistance MOSFET switch to reduce conduction losses. At light loads the device enters a power-save mode with reduced switching frequency, cutting quiescent current to the microamp range and achieving efficiencies above 80% even at 1 mA load, extending battery life in always-on IoT nodes.
For a wearable or IoT sensor hub, why is the QFN package of XPS62823DLCR advantageous over traditional through-hole regulators?
The QFN package of XPS62823DLCR provides a very small footprint, typically under 4 mm x 4 mm, with exposed thermal pad for efficient heat dissipation without heatsinks. Compared to a PDIP or SOP linear regulator, the QFN buck converter achieves far higher efficiency by switching rather than dissipating excess voltage, and the small size allows integration into wearable PCBs with board areas under 1 cm squared.
In a multi-rail embedded system, how does XPS62823DLCR handle transient load steps on a processor core rail?
XPS62823DLCR features a fast transient response with a high switching frequency, typically in the MHz range, which allows small output capacitors of a few microfarads to maintain output voltage deviation within 50 mV during load steps of hundreds of milliamps. This tight regulation keeps processor core voltages stable during burst compute cycles, preventing resets or clock errors in voltage-sensitive SoC designs.
What output voltage range can XPS62823DLCR regulate to and which processor supply rails does that cover?
XPS62823DLCR can regulate its output to voltages as low as 0.6 V and up to approximately 1.8 V, covering standard core supply rails such as 0.75 V, 1.0 V, 1.2 V, and 1.8 V used by modern application processors, FPGAs, and memory interfaces. The adjustable output is set via an external resistor divider, allowing the same IC to power multiple rail voltages across different board variants without changing the BOM.
