Unveiling new RPHM-0.5 non-isolated DC/DC switching regulator

RECOM extends its RPM series with the launch from the RPMH-0.5, a 0.5A non-isolated DC/DC switching regulator in a low-profile DOSA-compatible LGA package with an input range from 4.3V as much as 65V and five trim able output options.

With the launch from the RPMH-0.5 series, RECOM has expanded its selection of compact, non-isolated DC/DCs inside a standard 12.19 x 12.19 x 3.75mm DOSA-compatible thermally-enhanced low profile LGA package. With 0.5A output, five trimmable fixed outputs can be found: 3.3V (+10%/-20%), 5V (+10%/-20%), 12V (+10%/-40%), 15V (+10%/-40%) or 24V (+17%/-37%). Input voltage range is 1V-1.5V over the set output up to 65V, making the parts suitable for systems operating on nominal 5, 12, 24 or 48V rails. Excellent thermal management implies that the RPMH-0.5 series operates from -40°C as much as 95°C (100°C) ambient with full load and convection cooling only. Efficiency can be 89% allowing the entire 500mA output current to become delivered over the entire input voltage range.

Efficiency is also excellent at very low loads, which, combined with very low quiescent current right down to 16uA (3.3V and 5V versions), makes this series ideal for applications which have 'sleep' modes for example microcontrollers and transceivers. The RPMH also features 6-sided shielding for low radiated EMI so class B EMI compliance is achieved with a simple low cost line inductor. Additional features include full protection (UVLO, SCP, OCP) along with power sequencing, soft start, on/off control, remote sensing, along with a power good signal.

Steve Roberts, Innovation Manager at RECOM comments: “Because from the adoption of 48V in soft hybrid vehicles, we see the cost of Li-ion batteries falling and 48V power rails increasingly being used in a number of other application areas. When down-conversion to some lower voltage is essential, the RPMH-0.5 series is an ideal fit with its wide input range as much as 65V”.
