Technical Guides
The initial reviewed technical guides are available for automotive buck-converter selection, vehicle input transients and 24 V / 48 V wide-input conversion. Each guide addresses a defined engineering question with practical review criteria. Further engineering resources remain in preparation.
How to Select a Buck Converter for Automotive Applications
A requirements-led framework for selecting an automotive buck converter. The guide connects the vehicle input envelope and load profile with conversion ratio, operating mode, magnetics, thermal limits, EMI layout, protection, qualification evidence and supply-lifecycle review.
Explore 02 /Automotive Power Supply Design: Input Voltage, Load Dump and Transients
An engineering framework for defining automotive power-input conditions beyond nominal battery voltage. It organizes supply states, transient categories, reverse polarity, front-end protection, regulator survivability, energy handling, layout and validation without asserting compliance to an unspecified standard.
Explore 03 /Wide-Input DC-DC Design for 24V and 48V Systems
A practical design framework for non-isolated wide-input DC-DC conversion in 24 V and 48 V systems. It covers source-envelope definition, topology boundaries, device-voltage margin, high-ratio switching, magnetics, thermal and EMI decisions, protection and validation.
