Step-down regulator operates from 24-to-48-V inputs, emits little EMI
Analog Devices announces the Power by Linear LTM4653, 58VIN step-down µModule Regulator. The LTM4653 can safely operate from unregulated or fluctuating 24V to 48V input supplies in noisy environments such as factory automation, industrial robotics, communication infrastructure and avionics systems. The LTM4653 integrates input and output filters in a package, enabling the device to meet the EN55022 […]
Power system manager combines digital measurements, PMBus interface computation
Analog Devices announces the Power by Linear LTC2972, a 2-channel power system manager, featuring current, power and energy monitoring of the intermediate bus input to point-of-load (POL) converters. Monitoring circuit board power and energy use is a prerequisite for managing, optimizing and reducing their consumption in order to lower server rack and data center cooling and […]
150-V dual synchronous step-down DC/DC controller eliminates external surge protection devices
Analog Devices announces the Power by Linear LTC7810, a high voltage non-isolated 150-V dual synchronous step-down DC/DC controller that drives all N-channel MOSFET power stages. Its 4.5V to 140V (150V abs max) input voltage range is designed to operate from a high input voltage or from an input that has high voltage surges, eliminating the need […]
Dual 15-A/single 30-A µmodule regulator with stacked inductor package is 96% peak efficient
Analog Devices announces the Power by Linear LTM4662, a dual 15A or single 30A step-down µModule regulator in a BGA package with an exposed stacked inductor for improved thermal dissipation properties. The remaining components, the MOSFETs, DC/DC controller and supporting components, are overmolded and the complete device is housed in a 11.25mm x 15mm x 5.74mm BGA […]
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 […]
Dual-channel, 1.6-A synchronous buck driver simplifies LED dimming
Analog Devices announces the Power by Linear LT3964, a dual channel, 36V, high efficiency, synchronous, step-down LED driver with internal 40V, 1.6A power switches and an I2C interface that simplifies LED dimming control. The LT3964 operates with a wide 4V to 36V input range, and features two independently controlled LED drivers that switch at up to […]
Synchronous step-down switcher delivers 4 A with 94% efficiency
The LT8650S is a dual 4A, 42V input synchronous step-down switching regulator. It’s unique Silent Switcher2 architecture uses four internal input capacitors as well as two internal BST and a single INTVCC capacitor to minimize the area of the hot loops. Combined with very well controlled switching edges and an internal construction using copper pillars […]
Step-down regulator delivers 2 A from tiny 6.25 x 4-mm BGA package
The LTM8063 from Analog Devices is a 40VIN, 2A µModule step-down regulator in a tiny 6.25mm x 4mm BGA package. According to the company, the package size is 75% smaller than the existing equivalent product. With two 0805 size capacitors and two 0603 size resistors, the solution is only 70mm². The Silent Switcher architecture minimizes EMI emissions, enabling the […]
Step-down regulator supports N+1 current sharing
Analog Devices, Inc. is now offering the LTM4645, a 25A step-down regulator with the ability to current share multiple independent devices (N) where at least one LTM4645 is used as backup (+1) to ensure power availability if one device in this N+1 arrangement detects a fault and must be disconnected. For example, a 75A, 1V load […]
