The compact, open frame P783F-S non-isolated dc-dc converter series, offering 3 A of output current and no-load input current as low as 2 mA, has been designed to offer a high-performance alternative to linear regulators. The P783F-S dc switching regulator series is extremely efficient up to 97% and does not require a heat sink, making it ideal for applications where board space is at a premium and maximizing energy efficiency is a concern, such as industrial control and instrumentation.
