RPMH-0.5 DC-DC Switching Regulator

RECOM has introduced the RPMH-0.5 series of non-isolated DC/DCs in a standard 12.19 x 12.19 x 3.75mm DOSA-compatible thermally-enhanced low profile LGA package. These devices can operate in the input range of 4.3 V to 65 V, this makes them suitable for devices operating on nominal 5, 12, 24 or 48V rails. 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%).

Features of RPMH-0.5 Series

  • Wide Vin 4.3 to 65VDC
  • Low Profile (LxWxH = 12.19x12.19x3.75)
  • Wide operating temperature -40°C to +95°C at full load
  • Efficiency up to 89%, no need for heatsinks
  • 500mA output current
  • 6-sided shielding
  • Thermally and EMI enhanced 25 pad LGA package
  • Low profile

Note: More Technical details about the RPMH-0.5 DC-DC Converter can be found in the RPMH-0.5 Datasheet

The efficiency of the RPMH-0.5 series is excellent even at very low loads, which, combined with the very low quiescent current of 16µA (3.3V and 5V versions), makes them suitable for applications that have ‘sleep’ modes such as microcontrollers and transceivers. The devices are designed with 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, and a power good signal.
