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.
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. Thanks to its excellent thermal management the RPMH-0.5 series operates from -40°C up to 95°C (100°C) 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. Efficiency is also excellent at very low loads, which, combined with very low quiescent current down to 16μA (3.3V and 5V versions), makes the RPMH-0.5 series suitable for applications that have ‘sleep’ modes such as microcontrollers and transceivers.
For low radiated EMI the RPMH features a 6-sided shielding 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 and a power good signal.
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 behavior in overload or over temperature before design-in.
