50A regulator uses inductors as heat sinks, scalable to 250A
Analog Devices announces the Power by Linear LTM4678 dual 25A or single 50A step-down µModule regulator with PMBus digital interface. By stacking and exposing its two inductors on top of BGA package, the LTM4678 uses the inductors as heat sinks to transfer heat from inside, keeping the device cool. Onboard EEPROM and PMBus I2C enables a […]
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 […]
Isolated 4-port power source equipment (PSE) controller conforms to PoE++ specs
Analog Devices announces the Power by Linear LTC4291/92 isolated 4-port power source equipment (PSE) controller chipset, the first of its kind to pass a series of IEEE 802.3bt (PoE++) Power over Ethernet (PoE) conformance tests administered by Sifos Technologies. PoE naturally presents system and network engineers with PSE evaluation challenges. PSEs are multichannel, intelligent DC power […]
