Synchronous step-down silent switcher puts out 6 A, features ultra-low EMI/EMC emissions
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LT8640S, a 6A, 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. Combined with very well controlled switching edges and an […]
GaN power amplifiers target applications operating between 2 GHz and 6 GHz
Analog Devices, Inc. today announced a pair of high-performance gallium nitride (GaN) power amplifier (PA) modules which offer one of the highest power-density levels in their class, thus minimizing size and weight of the subsystem. The HMC7885 and HMC7748 broadband modules target applications operating between 2 GHz and 6 GHz, including test and measurement, communications, […]
+48V hot swap controller provides protection against system faults and system resets
Analog Devices, Inc. announced the availability of the ADM1272, an innovative +48V hot swap controller and PMBus™ power monitor. Designed for high-voltage system control up to 80V, the ADM1272 provides reliable plug-in board protection in mission critical systems, such as servers and communication equipment. Advanced system control and board power monitoring provide superior protection against system […]
PWM controllers with integrated 5 kV isolation and true secondary side isolation
Analog Devices, Inc. announced a series of three isolated pulse width modulation (PWM) controllers with integrated 5 kV isolation enabled by ADI’s award-winning iCoupler® technology. The ADP1071-1 and ADP1071-2 are isolated synchronous flyback controllers and the ADP1074 is an isolated synchronous active clamp forward controller. By integrating multiple functions such as overvoltage protection (OVP), output tracking, […]
