The MORNSUN K7803-500R3 is a DC DC converter designed as a linear regulator replacement, providing a regulated 3.3V output from an input voltage as low as 4.75V. It delivers up to 500mA of output current with a power rating of 1.7W and an efficiency of 86%, reducing heat dissipation compared to linear regulators.
This converter features short circuit protection (SCP) and is suitable for ITE (commercial) applications. It operates over a temperature range of -40°C to 85°C with derating. The component is housed in a compact 3-SIP through-hole module measuring 11.6mm x 7.6mm x 10.2mm, making it easy to integrate into board-level designs.
The K7803-500R3 carries approvals from CB, CE, and cURus agencies. It is intended for commercial electronic equipment where efficient step-down conversion from a higher DC voltage to 3.3V is required.
