The CUI Inc. VX7803-500-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, reaching up to 95% typical. The device supports a wide input voltage range of 4.75 Vdc to 36 Vdc and provides a stable 3.3 Vdc output at up to 500mA.
Key electrical specifications include a maximum output power of 1.65W, a typical efficiency of 86% at full load, and a maximum ripple and noise of 75mVp-p. The regulator operates with a switching frequency between 550 kHz and 850 kHz. It includes continuous auto-recovery short circuit protection and a no-load input current as low as 0.2 mA.
Designed for ITE (Commercial) applications, the VX7803-500-W operates across a wide temperature range of -40°C to +85°C. Its dimensions are 11.5mm x 9.0mm x 17.5mm, with a through-hole mounting type. The device is designed to meet safety standards such as EN 62368-1 and complies with CISPR32/EN55032 Class B for emissions.
