UST Models www.murata-ps.com 3W, Single Output DC/DC Converters PRODUCT OVERVIEW Rarely has a Series of low-power DC/DC lters within their package. Output transient converters been de ned by both low cost and response is a quick 200sec, while output ripple Murata Power Solutions made-in-the-USA quality and noise are typically 75mVp-p. and reliability. Our new UST Series of single-output These rugged modules are fully encapsulated DC/DCs achieves this best-of-both-worlds status with a thermally conductive potting compound that by implementing a proven circuit architecture contributes to their outstanding moisture/vibration (170-200kHz yback design) as a full, SMT-on-pcb resistance and impressive MTBF. They operate over assembly (including surface-mount magnetics) that the full 40 to +75C temperature range without is truly 100% automatically assembled. Packaged derating.
