Rutronik<\/a><\/strong> has added the new RPMH-0.5 series of 0.5A non-isolated DC\/DC switching regulators from Recom to its offering. They feature an input range from 4.3V up to 65V and five trimmable output options and come in a standard DOSA-compatible low profile LGA package. The DC\/DCs are available at Rutronik UK.<\/p>\n\n\n\n

Because of the increasing number of soft hybrid vehicles with 48V board net, the cost of Li-ion batteries are falling and 48V power rails are increasingly being used in many other application areas. Here, the RPMH-0.5 series is ideal for down-conversion to a lower voltage.<\/p>\n\n\n\n

With 0.5A output, five trimmable fixed outputs are available: 3.3V (+10%\/-20%), 5V (+10%\/-20%), 12V (+10%\/-40%), 15V (+10%\/-40%) or 24V (+17%\/-37%). Input voltage range is 1V-1.5V above the set output up to 65V, making the converters suitable for systems operating on nominal 5, 12, 24 or 48V rails. <\/p>\n\n\n\n

Thanks to its excellent thermal management the RPMH-0.5 series operates from -40\u00b0C up to 95\u00b0C (100\u00b0C) ambient with full load and convection cooling only. Due to its efficiency of up to 89% the full 500mA output current can be delivered across the entire input voltage range. <\/p>\n\n\n\n

Efficiency is also excellent at very low loads, which, combined with very low quiescent current down to 16\u00b5A (3.3V and 5V versions), makes the RPMH-0.5 series suitable for applications that have \u2018sleep\u2019 modes such as microcontrollers and transceivers.<\/p>\n\n\n\n

For low radiated EMI the RPMH features a 6-sided shielding so \u2018Class B\u2018 EMI compliance is achieved with a simple low cost line inductor. <\/p>\n\n\n\n

Additional features include full protection (UVLO, SCP, OCP) along with power sequencing, soft start, on\/off control, remote sensing and a power good signal.<\/p>\n\n\n\n

To complement RPMH-0.5 series Rutonik also offers the RPMH-0.5-EVM-1 from Recom for easy evaluation of control, power good, and sensing functions. It generates a constant output current of up to 0.5A from an external DC source, thus allowing the evaluation of all functions of the RPMH-0.5 as well as the behaviour in overload or over-temperature before design-in.<\/p>\n","protected":false},"excerpt":{"rendered":"
