A look at IGBT and silicon-carbide gate drivers from Tamura
Tamura is almost a hundred-year-old company and a broad magnetics manufacturer of current sensors, transformers, gate drivers, and dc-to-dc power modules. They have UL-approved drivers to go with IGBT or silicon-carbide power modules. They are introducing a new generation of gate drivers, which have much better performance than what was available before. The new units […]
High-efficiency surge stopper protects against 150-V transients
Analog Devices announces the Power by Linear LTC7862, a high efficiency switching surge stopper with overvoltage and overcurrent protection for high availability systems. The LTC7862 drives an N-channel power MOSFET stage. During normal operation the LTC7862 passes the input voltage through to the output with minimal conduction loss. When an input overvoltage condition occurs, the LTC7862 starts […]
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 […]

PWM buck converters integrate MOSFETs, deliver low parasitics
ON Semiconductor has announced the release of three new highly-efficient mid-voltage PWM buck converters. Supporting a wide input voltage range of 4.5 V to 65 V, an output current of up to 10 A and output power of 100 W, ON Semiconductor’s new FAN6500X family of buck converters combines the time-tested fixed frequency control scheme with […]
Wide-VIN DC/DC buck regulators simplify design of industrial power supplies
Texas Instruments introduced two wide-VIN synchronous SIMPLE SWITCHER DC/DC buck regulators in ultra-small HotRod quad flat no-lead (QFN) packaging. The highly integrated 3-A LMR33630 and 2-A LMR33620 step-down voltage converters feature the industry’s best full load efficiency – 92 percent – for rugged and reliable industrial power supplies with switching frequencies up to 2.1 MHz. Used in conjunction with TI’s WEBENCH Power Designer, the converters […]
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 […]
