Step-down DC/DC controller draws only 9 µA quiescent, targets burst-mode battery apps
Analog Devices announces the Power by Linear LTC3894, a high voltage step-down DC/DC controller that draws only 9µA quiescent current with the output enabled in Burst Mode operation. Its wide 4.5V to 150V input voltage range can effectively eliminate the need for external surge suppression devices. The LTC3894’s 100% duty cycle capability and externally adjustable power good window […]
Synchronous boost LED controller features 60-V output
Analog Devices announces the Power by Linear LT3762, a 60V output, high efficiency, synchronous, boost LED driver controller with a programmable internal LED PWM signal generator and spread spectrum frequency modulation that yield low EMI noise. The versatile LT3762 includes a rail-to-rail current sense amplifier, enabling high side or low side current sensing that in addition […]
Synchronous step-down switcher delivers 95% efficiency at 2 MHz, emits little EMI
Analog Devices announces the Power by Linear™ LT8642S, a 10A, 18V input synchronous step-down switching regulator. Its Silent Switcher® 2 architecture uses two internal input capacitors as well as internal BST and INTVCC capacitors to minimize the area of the hot loops. The LT8642S dramatically reduces EMI emissions as a result of its controlled switching edges and its internal […]
Audio bus transceivers handle multiple microphones for auto infotainment apps
Analog Devices, Inc. (ADI) announced today three enhanced Automotive Audio Bus (A2B®) transceivers that deliver unprecedented capability to tailor system-level performance to even the most stringent electromagnetic compatibility (EMC) requirements. The new AD242x series offers configurable transmit power levels, enabling the developer to match system performance to specific OEM EMC requirements – a key design criterion […]
Teardown: The Apple Sport watch
Apple recently came out with the Series 3 version of its watch. We can get an idea of how the Series 3 goes together from a teardown analysis of Apple’s earlier Sport model. The Sport model we analyzed has an aluminum case but the watch is also available in stainless steel. It measures about 39 […]
Managing EV batteries squeezed into odd shapes
Automakers are forced to fit EV batteries into nooks and crannies in an effort to maximize driving range. The resulting convoluted layouts call for a wireless approach to managing cells. GREG ZIMMER | Linear Technology Corp., now part of Analog Devices Inc. Lithium-Ion batteries require considerable care if they are expected to function reliably over […]
Rugged RS485 transceiver meets IEC Level 4 ESD standard
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC2862A, an enhanced version of the widely accepted LTC2862 ±60V tolerant RS485/RS422 transceiver that released several years ago. Both of these half-duplex transceivers eliminate field failures without the need of costly external protection devices by protecting practical RS485 systems from installation cross-wiring faults, ground […]
2-V input synchronous step-down switching regulator features super-low EMI/RFI emissions
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LT8609S, a 2A (3A Peak), 42V input synchronous step-down switching regulator. Its unique Silent Switcher® 2 architecture uses two internal input capacitors as well as internal BST and INTVCC capacitors to minimize the area of the hot loops. The LT8609S design dramatically reduces EMI/EMC […]
High-power fixed-ratio DC/DC controller eliminates power inductor in non-isolated intermediate bus converters
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC7820, a high power fixed ratio charge pump DC/DC controller that eliminates the power inductor in a non-isolated intermediate bus converter, allowing up to a 50% reduction in circuit size and up to 4000W/in³ power density. The LTC7820 drives external MOSFETs in voltage divider, […]
