Linear Tech's new controller saves design time, board space

Linear Technology Corp. released a push button controller that provides control for dc-dc converters, processor interrupt logic and adjustable on/off timers.

According to the company, the LTC2950 easily solves the inherent bounce problem associated with all mechanical contacts, while also enabling power supply converters and releasing a processor once the supply is fully powered up. When powering off, the device interrupts the system processor to alert it to perform the necessary power down and housekeeping tasks. Once the system completes the turn off operations, it can command the LTC2950 to immediately disable power.

The LTC2950 operates over a wide 2.7V to 26V input voltage range to accommodate a wide variety of input power supplies. The 6?A supply current makes the IC suitable for battery powered applications. Two versions of the LTC2950 are available to accommodate either positive or negative enable polarities. The rugged push button input pin is designed to operate in noisy environments and it can withstand ESD strikes of up to 10kV.

Offered in an 8-pin 2-by-3mm DFN package, the LTC2950 saves design time, as well as board space for portable instruments and handheld products. Specified over the commercial and industrial temperature range, pricing begins at $1.75 each for 1,000-piece quantities.
