The PXO78B-500-M series is an ultra-thin, open-frame non-isolated DC-DC converter series that has been designed to offer a high performance alternative to linear regulators. Housed in a compact SMT package, this series features low ripple and noise and a no-load input current as low as 0.5mA. Additionally, it does not require a heat sink, making it ideal for applications where board space is at a premium and energy efficiency is a concern.
