Overview
The CATVolt FlexConvert 28 is an automatic buck/boost DC-DC converter module: feed it anything from 3.5 to 28 V and it holds an adjustable output between 1.25 and 26 V at up to 1 A — stepping down or up as needed, switching between the two seamlessly as the input drifts.
That auto-ranging is the point. A battery-fed 12 V rail sags as the cells discharge; a fixed buck converter drops out, but the FlexConvert rides through, boosting when the input falls below the setpoint. It suits battery-powered field equipment, prototypes and any small load that must not brown out.
Like everything in CAT.store, the FlexConvert 28 is specified and supplied by the engineering practice behind PRODUCT.design: we confirm the fit for your application before we quote, and every quote is confirmed within one business day.

Setup Notes
Set the output with a multimeter before connecting the load, observe polarity, and keep the draw within 1 A. Give the module airflow when running near its limit.
Load bigger than 1 A, or need a fixed enclosed unit instead of an open module? Ask us — the StepDC 100 or a sized alternative may fit better.
