Configurable as quad, triple, dual or single output, the LTM4643 quad output step-down µModule [micromodule] (power module) regulator deliver, respectively, 12A, 6A & 6A or 9A & 3A, or 4 x 3A from a 9 x 15 x 1.82 mm ultrathin LGA package. by Graham Prophet @ edn.com: This flexibility enables system designers to rely […]
Regulator offers independent outputs
https://www.electronics-lab.com/regulator-offers-independent-outputs/
Susan Nordyk @ edn.com writes: Housed in a 15×9×2.42-mm over-molded BGA package, the LTM8049 µModule dual-output DC/DC converter from Linear Technology is configurable for a combination of SEPIC and/or inverting operation by simply grounding the appropriate output rail. All that is needed to complete the design are input and output capacitors and a few resistors—a […]
Dual input, 2.5A step-down DC/DC achieves 95% efficiency
https://www.electronics-lab.com/dual-input-2-5a-step-dcdc-achieves-95-efficiency/
by Graham Prophet @ edn.com: LTC3126 is a 2.5A, 2.4V to 42V input, synchronous step-down switching regulator with integrated dual input PowerPath control. Its power stage topology enables operation from either of two independent power sources, with seamless, internally controlled transitions between inputs to ensure a stable output voltage during hot-plug and power source disconnect […]
LTC3623 – Switching regulator doubles as Class-D audio amplifier
https://www.electronics-lab.com/ltc3623-switching-regulator-doubles-class-d-audio-amplifier/
Clemens Valens @ elektormagazine.com discuss about LTC3623 switching regulator which can be used as Class-D Audio Amplifier. Sure thing, Elektor has published several designs of adjustable power supplies based on switching regulators, so we know that doing this properly in a reproducible way and without making things overly complex requires some serious head scratching. The […]
Reverse engineering a server CPU voltage regulator module
https://www.electronics-lab.com/reverse-engineering-server-cpu-voltage-regulator-module/
Andy Brown wrote a detailed article on reverse engineering a CPU voltage regulator: A recent ebay fishing expedition yielded an interesting little part for the very reasonable sum of about five pounds. It’s a voltage regulator module from a Dell PowerEdge 6650 Xeon server. I originally bought this because I had the idea of salvaging […]
LT3086 – 40V, 2.1A Low Dropout Adjustable Linear Regulator with Monitoring and Cable Drop Compensation
https://www.electronics-lab.com/lt3086-40v-2-1a-low-dropout-adjustable-linear-regulator-monitoring-cable-drop-compensation/
Graham Prophet @ www.edn-europe.com discuss about LT3086 LDO. The 40V, 2.1A low dropout linear regulator (LDO) includes current monitoring with externally settable current limit and temperature monitoring with external control of thermal limit temperature. The device includes a programmable power-good status flag, cable drop compensation and easy paralleling. The current reference in the LT308x LDO […]
