Linear regulator protects load with rapid output discharge

Linear regulator protects load with rapid output discharge
A linear regulator, delivering up to 100mA of continuous output current with a 250mV dropout voltage at full load, has been introduced by Linear Technology. Featuring an internal NMOS pull-down, the LT3061 discharges the output voltage if either the SHDN pin is driven low or the input voltage is turned off. With this rapid output discharge, the load is protected in applications requiring power conditioning on both start-up and shutdown.

Power divider provides broad bandwidth in phase splitting

Power divider provides broad bandwidth in phase splitting
A Wilkinson power divider, introduced by Knowles, provides in-phase power splitting or combining over a broad bandwidth. This is achieved by application of precision thin film fabrication with integrated resistors, coupled with high permittivity ceramic materials.

Synchronous buck regulator targets servers and networking

Synchronous buck regulator targets servers and networking
Capable of delivering high current due to low RDS(on) internal switches, the A8672 synchronous buck converter has been introduced by Allegro MicroSystems. Utilising valley current mode control to achieve very short on-times, the converter targets applications such as servers and networking systems requiring 5 or 12V input step down conversions at high output current.

Single output modules feature a 1.6-53V output voltage range

Single output modules feature a 1.6-53V output voltage range
To meet the market demand for more output wattage combinations, MEAN WELL have added a 210 and 360W single output module to its Modular Series line. The MS-210 and MS-360 provide 11 nominal DC output voltages, including 2, 3.3, 5, 7.5, 12, 15, 18, 24, 27, 33 and 48V. This can be further adjusted by the module's potentiometer or the remote margin function which provides an output voltage range of 1.6-53V.

18V eFuse offers protection & extends battery life

18V eFuse offers protection & extends battery life
Extending battery life in portable and adapter-powered devices, the TPS2594x family of bidirectional protection switches has been introduced by Texas Instruments. The company claims that the devices are the industry’s smallest bidirectional 18V, 5A protection switches with high power efficiency. The devices not only extend battery life in portable applications, but reduce solution size and extend battery life in enterprise and client SSDs.
