DC/DC converters target connected-vehicle applications

May 31, 2016 // By Graham Prophet
Low profile and high power density underpin the desgin appraoch of these converters, which hve been configured to power IoT in automotive applications with ultra-high efficiency.

Based on a highly integrated components platform and low-profile planar magnetics, Powerbox’s ENA100 (100W) and ENA200 (200W) are packaged in a plastic enclosure, which is IP21-compliant; the boards are conformal coated to withstand high humidity, complying with the challenging environments found in the automotive industry.


To guarantee the highest levels of efficiency and reliability, the ENA100 and ENA 200 power stage uses specific components selected for robustness and high-reliability data and operated within a safe-band area. The series comes with galvanic isolation of 500 VDC and built-in protections and filtering, making products ready to use without additional components.

The automotive industry comprises of a large segment of varying applic


As members of the Powerbox Automotive Line, the ENA100 and ENA200 units have been designed in response to the automotive electronics equipment manufacturer’s demand for standardised DC/DC converters built-in low profile packaging, lower than 20 mm (0.8 in.), isolated cases with an IP-class of 21, galvanic isolation, low conducted and radiated EMI and sustaining 2 kV surges along with a requirement for simple installation and the ability to upgrade when more power is required, if new equipment is added. The company comments that emergency vehicles and new long-range bus fleets are requiring very flexible and reliable power sources to supply local voltages to demanding applications such as radio localisation and on-board video systems.
