Pico 5SMV500 5V to 500V 1.25W SMD High Voltage DC-DC Converter
The Pico 5SMV500 is an ultra-compact surface-mount high-voltage DC-DC converter designed to generate a 500V output from a nominal 5V input. It delivers up to 1.25W and 2.5mA in a 0.5 × 0.5-inch package, making it suitable for space-constrained high-voltage circuits.
The 5SMV500 is an isolated proportional converter rather than a regulated power supply. Its output voltage varies with input voltage and load, so the module is best suited to applications that can tolerate this variation or use external voltage-control and feedback circuitry.
