Self-protected MOSFETs from Diodes Incorporated raise protection levels for inductive loads
Diodes Incorporated has announced further additions to its IntelliFET range of self-protected MOSFETs. The 60V, 75m? (typical) rated single N-channel ZXMS6006DG/SG and dual N-channel ZXMS6006DT8 provide thermal shutdown, short circuit, over voltage, over current and input ESD protection facilities enabling circuit designers to dramatically increase circuit reliability. Suiting automotive and industrial applications, these self-protected MOSFETs...
TI introduces Green Rectifier controller for 5-V power supplies
Texas Instruments introduced a new power management controller and driver for standard and logic-level N-channel MOSFETs used for low-voltage, secondary-side synchronous rectification. The UCC24610 Green Rectifier™ controller improves power supply efficiency as much as five percent, and reduces primary-side power loss in 5-volt AC/DC adapters and bias supplies.
60V Input Synchronous Step-Down DC/DC Controller Draws Only 50µA in Battery-Powered Systems
Linear Technology has introduced the LTC3891, a high voltage synchronous step-down DC/DC controller that draws only 50µA in standby mode with the output in regulation. The 4V to 60V input supply range is designed to protect against high voltage transients, continue operation during automotive cold crank and cover a broad range of input sources and battery chemistries. The output voltage can be set from 0.8V to 24V at output currents up to 20 amp...
