Regulate output voltage without an optocoupler

Regulate output voltage without an optocoupler
Suited for power levels up to 200W, Linear Technology has introduced the LT8310 primary-side synchronous forward controller which operates over an input voltage range of 6-100V. Without the use of an optocoupler, output voltage regulation of ±8% can be achieved, rising to ±1.5% regulation when using an optocoupler.

200mA linear regulator features 300mV dropout voltage

200mA linear regulator features 300mV dropout voltage
A linear regulator, providing high voltage, low noise and low dropout voltage, has been released by Linear Technology. Featuring a wide input voltage range of 1.6-45V, the LT3062 delivers adjustable output voltages from 0.6-40V. Programmable noise operation of only 30µVRMS across a 10Hz-100kHz bandwidth, along with a reference soft-start functionality which prevents output voltage overshoot at turn-on, is provided by a single capacitor.

AC/DC modules can be adjusted over a ±20% range

AC/DC modules can be adjusted over a ±20% range
The PFE-S series of AC/DC full-brick power modules, manufactured by TDK Corporation, has been updated. Now available in 12V, 28V and 48V nominal outputs, the PFE-SA series can be adjusted over a ±20% range. With the PFE300SA, full power can be delivered with a baseplate temperature of between -40 and +100°C. The 12V PFE500SA has a maximum base-plate temperature of 85°C, while the 28V and 48V models deliver the same output at temperatures up to 100°C.

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.
