Wide-input range buck-boost controller needs no external surge suppression devices
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 […]
Bidirectional current DAC adjusts output voltage of virtually any dc/dc regulator
Analog Devices announces the Power by Linear LTC7106, a PMBus I2C controlled precision bidirectional current DAC designed to adjust the output voltage of virtually any DC/DC regulator. Through its PMBus compatible interface, the LTC7106 receives a 7-bit serial code and converts it to a bidirectional (source, sink) output current. When the current is fed into the […]
Hot swappable supercapacitor backup power controller provides uninterrupted power
Analog Devices announces the Power by Linear LTC3351, a supercapacitor charger and backup power controller IC that includes hot-swap front-end protection and all the features necessary to provide a complete, standalone capacitor-based backup power solution. The LTC3351’s integrated hot swap controller and circuit breaker use N-channel MOSFETS to provide a low loss power path from the […]
Low-power active mixer delivers 7-GHz bandwidth, 20 dBm OIP3
Analog Devices announces the LTC5562, a low power, high performance active double-balanced mixer, capable of 50Ω matching over a very wide frequency range of 30MHz to 7GHz. This versatile mixer can be used in either frequency upconversion or downconversion applications, with outstanding conversion gain of 2dB. The device runs on a single 3.3V supply rail, drawing 40mA […]
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. […]
Solid-state temperature sensing, Part 2: application
In Part 1, we looked at the basic principle and function of the solid-state temperature sensors, as well as the first widely available model, the AD590. Part 2 looks at some application considerations. Q: What are the interface considerations? A: A basic solid-state sensor has a PTAT current-only output. This means that the subsequent circuitry, […]
Solid-state temperature sensing, Part 1: principles
Temperature is by far the most commonly measured physical parameter in industrial, commercial, and even residential settings. It’s obviously about much more than just “what’s the temperature, so I will know what coat to wear?” Temperature readings are needed to control processes and systems via a negative feedback loop, PID algorithms, and comparators, References 1 […]
