The CUI Inc. VX7809-500-W is a non-isolated DC switching regulator designed as a pin-out compatible replacement for linear regulators. It features a low profile and high efficiency up to 93%, making it suitable for various applications.
This model provides a nominal 9V output voltage with a maximum current of 500mA and a maximum output power of 4.5W. The operating input voltage range is 4.75V to 36Vdc. Key electrical specifications include a typical no-load input current as low as 0.2mA, a switching frequency between 550kHz and 850kHz, and load regulation of ±1.5% maximum.
The regulator operates within a wide temperature range of -40°C to +85°C (with derating). It includes output short circuit protection with auto-recovery. The dimensions are 11.5mm x 9.0mm x 17.5mm, and it is designed for through-hole mounting.
Compliance includes EN safety approvals and adherence to CISPR32/EN55032 Class B for conducted and radiated emissions. It also meets IEC/EN61000-4-2 ESD standards.
