Linear Technology Corporation introduces the LTC2974 power supply manager with EEPROM for complete digital management of power supply systems with four or more power rails. The LTC2974 utilizes an I²C interface and PMBus command set to monitor and control positive or negative supplies, providing rapid troubleshooting and debug capabilities during power system design, development, production and failure analysis.

Linear Technology Corporation introduces the LTC2955 pushbutton on/off controller that manages 1.5V to 36V system power via a pushbutton interface or the presence of a supply. Unlike typical pushbutton controllers that initiate system power-ups only with the toggle of a pushbutton, the LTC2955 automatically turns on a system when power is applied from a primary or secondary supply, such as a wall adapter or car battery.

Linear Technology has introduced the LT4356, an overvoltage protection regulator, with overcurrent protection and inrush current limiting for high availability systems. In applications where electronic systems must cope with high voltage surges of short duration, such as load dump in automobiles, the LT4356 provides solid front-end protection for valuable, safety critical downstream components. The wide input operating range of 4V to 80V enables ...

Linear Technology has introduced the LTC4224, a compact, low voltage Hot Swap controller for protecting boards and backplanes that use two 1V to 6V voltage supplies. Systems, including fiber optic networks, will benefit from the simplified control with independent turn-on and adjustable ramp of the two supplies. In recent years, multisource agreements like XENPAK have defined fiber optic transceiver modules that provide transmission rates up to 1...

Linear has today introduced the LTC4364, a surge stopper with ideal diode, providing compact and low-loss protection for 4V to 80V electronics in industrial, avionics and automotive systems. The surge stopper shields downstream electronics from input overvoltages and overcurrent, enabling continuous operation through transient surges. Overcurrent limiting protects the system and supply from short-circuits at the load. Unique to the LTC4364 is ...

Linear Technology has introduced the LT3845, a 4V to 60V input range, synchronous DC/DC step-down controller with adjustable 100kHz to 500kHz operating frequency. At higher frequencies users can implement a smaller inductor and capacitors, or at lower frequencies they can optimize the efficiency of the circuit. For noise- sensitive applications, the LT3845 can be synchronized to an external clock from 100kHz to 600kHz. The minimum 4V input mainta...

Linear Technology has introduced the LTC3823, a synchronous step-down DC/DC controller with differential output voltage sensing, fast transient response, integrated phase-lock loop synchronization and output voltage tracking. The differential amplifier provides true differential remote output voltage sensing of both the positive and negative terminals. This enables high accuracy regulation in high current applications where IR losses occur throug...

Linear Technology Corporation annonce la version de classe H du LTC3872, un contrôleur DC/DC, élévateur, à fréquence de fonctionnement fixe de 550 kHz, de petite empreinte. Il est spécifié sur la gamme de températures de jonction de – 40°C à 150°C.

Linear Technology Corporation annonce le LT3748, un contrôleur DC/DC, à récupération d'énergie, isolé, forte tension d’entrée, qui simplifie grandement la conception d’un convertisseur DC/DC isolé. Il ne nécessite pas de photocoupleur, ni d’un troisième enroulement ni d’un transformateur d’isolement dans la boucle de régulation puisqu’il peut détecter directement la tension de sortie à partir du signal présent sur l’en...

Linear Technology annonce le LT3754, un pilote de DEL utilisant un contrôleur DC/DC, en mode élévateur, pouvant piloter jusqu’à 45 V des DEL de 50 mA par canal. Son contrôleur DC/DC interne, en mode élévateur, 1 MHz, 60 V, est conçu pour piloter à courant constant jusqu’à 160 DEL blanches. A partir d’une tension de 12 V en entrée, le LT3754 peut piloter 16 canaux, chacun comprenant jusqu’à 10 DEL blanches en série, de 50 mA, ...
