What are the key features of L6920DC?
- Step-up (boost) DC-DC converter with 1 MHz switching frequency for compact filter design
- Wide input voltage range of 0.8 V to 5.5 V enabling battery-powered applications
- Up to 0.9 A output current with voltage-mode PFM control for high light-load efficiency
What is L6920DC used for?
The L6920DC is well suited for portable consumer electronics, IoT sensor nodes, and wearable devices that require stepping up a single-cell Li-ion or alkaline battery voltage to a regulated supply rail. Its 1 MHz switching frequency minimizes external passive component size, making it ideal for space-constrained PCB designs. The device is also used in medical handheld instruments and wireless modules where low quiescent current and adjustable output are essential.

Frequently Asked Questions
What input voltage range does the L6920DC support for boost operation?
The L6920DC accepts an input voltage from 0.8 V to 5.5 V, with a nominal operating point at 2 V, making it suitable for single-cell alkaline, NiMH, or Li-ion battery rails typically ranging 1.0 V to 4.2 V in portable systems.
How does the L6920DC's 1 MHz switching frequency benefit PCB design?
Operating at 1 MHz allows designers to use smaller inductors and capacitors—often below 10 µH and 10 µF respectively—reducing overall PCB footprint significantly compared to lower-frequency converters in size-critical applications like wearables.
In which package does the L6920DC come and what are its pin count and body dimensions?
The L6920DC is housed in an 8-pin MSOP (S-PDSO-G10) package with a compact body approximately 3 mm × 3 mm, offering 10 pads in a small-outline footprint that suits high-density portable circuit boards.
When would L6920DC be preferred over a linear regulator in a battery-powered design?
When output voltage must exceed the input battery voltage—for example, boosting a 1.5 V alkaline cell to a 3.3 V rail—a linear regulator cannot perform this conversion, whereas the L6920DC step-up topology delivers up to 0.9 A with high efficiency at 1 MHz.
