The reliability of board-mounted dc/dc converters is important to understand and quantify. It’s a measure of the frequency of system or device failures as a function of time. Reliability is the observed failure rate and is defined as either the time between two failures (in hours), called the Mean Time Between Failures (MTBF), or the […]

Low-cost non-isolated POL regulator modules provide up to 2 A
Introducing the SVR surface mount and VR through-hole, non-isolated DC-DC switching regulators. With efficiencies of up to 96% and operating temperatures of -40°C to +85°C, the Point of Load (PoL) devices are ideal as replacements for low-efficiency linear regulators. They operate from a wide input range of up to 36V and feature a low quiescent […]
EMC/EMI design and the use of board-mount dc/dc converters
Electromagnetic compatibility (EMC) and electromagnetic interference (EMI) are system-level considerations that have implications for power system design, especially when multiple board-mounted dc/dc converters are used in a distributed power architecture (DPA). EMC/EMI is a multidimensional consideration and includes differential- and common-mode noise on both the input and output of the converter radiated and conducted noise […]
Half-bridge PCBs help evaluate GaN drivers, transistors
GaN Systems announced the release of two 650V half-bridge daughter cards (30A and 60A), which provide an ultra-versatile platform to evaluate GaN drivers and transistors. The evaluation cards are available in two power levels, up to 3kW (GS-EVB-HB-66508B-RN) and up to 6kW (GS-EVB-HB-66516T-RN), and include the Renesas RAA226110 low-side GaN FET driver. These cards are the industry’s […]
Thermal management considerations for board-mounted dc/dc converters
System-level thermal design is equally important to the electrical specifications of board-mounted dc/dc converters. And the growing use of variations on a distributed power architecture (DPA) increases the complexity of thermal design. A single multiple-output ac/dc power supply is used to power the various loads in a conventional power architecture. The use of a centralized […]
Specifying board-mounted dc/dc converters
The specification of board-mounted dc-dc converters is an important and detailed process. Correctly implemented, it results in a cost-effective solution that meets all the needs of the application. Incorrectly specified dc/dc converters can result in a more costly device than necessary and/or a device that is not suited for the application. This FAQ will review […]
Reference design lets secondary MCU control primary power
In modern offline AC-DC power solutions, programmability and adaptive control offer the flexibility and intelligence needed by smart home devices to better interface with their power systems. In these systems, a secondary side microcontroller (MCU) is typically not capable of starting a system without the use of a separate bias power supply. A new reference […]
