2-3A, 42-Vin Silent Switcher offers low-EMI regulation
https://www.electronics-lab.com/2-3a-42-vin-silent-switcher-offers-low-emi-regulation/
LT8609S is a 2A (3A Peak), 42V input synchronous step-down switching regulator. The synchronous step-down Silent Switcher 2 Delivers 93% efficiency at 2 MHz with ultralow EMI/EMC emissions. By Graham Prophet @ eedesignnewseurope.com: The LT8609S design reduces EMI/EMC emissions due to very well controlled switching edges, its internal construction with an integral ground plane and […]
20V, 4 MHz, synchronous 2x 6A step-down regulator in 20 sq mm
https://www.electronics-lab.com/20v-4-mhz-synchronous-2x-6a-step-regulator-20-sq-mm/
Graham Prophet @ eedesignnewseurope.com presents the LTC3636 and LTC3636-1 synchronous step-down regulator from Linear: LTC3636 and LTC3636-1 are high efficiency, 4 MHz synchronous dual output buck regulators that incorporate a constant frequency/controlled on-time, current mode control scheme with phase lockable switching frequency. Their design architecture reduces conducted and radiated emissions. 20V, 4 MHz, synchronous 2x […]
SEPIC/Ćuk converter sprouts second output
https://www.electronics-lab.com/sepiccuk-converter-sprouts-second-output/
by Gheorghe Plasoianu @ edn.com Many applications require positive and negative supply voltages, with only one voltage requiring tight regulation. This Design Idea describes a dual-output, hybrid SEPIC–Ćuk converter whose positive output voltage can be lesser or greater than the input voltage. The unregulated negative output is a mirrored replica of the positive output. SEPIC/Ćuk […]

LT8641 – 65V, 3.5A Synchronous Step-Down Silent Switcher
https://www.electronics-lab.com/lt8641-65v-3-5a-synchronous-step-silent-switcher/
The LT8641 is a monolithic, constant frequency, current mode synchronous (external schottky diode is not necessary) step-down switching regulator. Its 3V to 65V input voltage range makes it ideal for 12V or 24V automotive and industrial applications. It delivers up to 3.5A of continuous output current and peak loads of 5A. Output voltages can be […]
Step‐up DC/DC converters with built‐in inductors and control ICs
https://www.electronics-lab.com/step%e2%80%90up-dcdc-converters-built%e2%80%90in-inductors-control-ics/
Measuring 2.5×2.0×1.0mm, the newly‐developed XCL102/XCL103 series of step‐up micro DC/DC converters is designed with built‐in inductors and control ICs. By Julien Happich @ edn-europe.com: The use of built‐in inductors also allows PCB layouts to be simplified, minimizing unwanted radiation noise and operational trouble. The input voltage can be selected from 0.65V (operation hold voltage) to […]
