Analog Devices announces the Power by Linear LTC3777, a 150V high efficiency (up to 99%) 4-switch synchronous buck-boost controller, which operates from input voltages above, below or equal to the regulated output voltage. Its 4.5V to 150V input voltage range operates from a high input voltage source or from an input that has high voltage surges, […]

Regulator module powers FPGAs, GPUs, ASICs
Analog Devices announces the Power by Linear LTM4646, a dual 10A or single 20A output, step-down µModule® point-of-load regulator from 5V or 12V input supply rails. The LTM4646 includes the inductors, MOSFETs, a DC/DC controller and supporting components, and is housed in an 11.25mm x 15mm x 5.01mm BGA package. Compared to the prior 2 x single […]
High-frequency, triple-output synchronous converter maintains outputs during automotive cold cranking
Analog Devices announces the Power by Linear LTC7815, a high frequency (up to 2.25MHz) triple output (buck, buck, boost), synchronous converter that maintains all output voltages in regulation during automotive cold crank conditions. A 12V automotive battery can droop to less than 4 volts during engine restart or cold crank, causing reset of infotainment systems and […]
DC/DC controller merges switched-capacitor circuit, synchronous step-down controller to shrink package size
Analog Devices, Inc. today announced the Power by Linear LTC7821, an industry first hybrid step-down synchronous controller that merges a switched capacitor circuit with a synchronous step-down controller, enabling up to a 50% reduction in DC/DC converter solution size compared to traditional step-down solutions. This improvement is enabled by a three times higher switching frequency without compromising efficiency. […]

Top microcontroller stories of 2017
Here are the power electronics features that got the most interest from readers in 2017. What is an open drain? Open-collector and -drain devices sink current when controlled to one state and have no current flow (i.e., output a high impedance state) in the other state. It is fairly common to […]
