Step-up Switching Regulator with Integrated Current Limit Schematic Circuit Diagram

In the form of the LT1618, Linear Technology (www.lineartech.com) has made available a step-up switching regulator with a current limit mechanism. This makes it easy to protect an otherwise not short-circuit-proof switching regulator with a current limit mechanism. This makes it easy to protect an otherwise not short-circuit-proof switching regulator: the input voltage is always[…]

Audible continuity tester

  Whatever the latest trend in digital multimeters. no electronics workshop is complete without a continuity tester for fast and reliable testing of connections, components, and PCB tracks. The little instrument discussed here is an audible continuity tester whose output frequency is determined by the resistance measured. Handheld and extremely simple to use, the tester[…]
