There are many small applications where it would be preferable to power a device directly from an RS232 (V.24) interface, avoiding a mains power supply. Most ICs require 5 V, and the interface can ...
Semtech Corp. has received MIL-PRF-19500/406 qualification from Defense Supply Center Columbus, (DSCC) of its brand new 1.5W Zener diode voltage regulator platform. Semtech Corp. has received ...
Figure 2 Bootstrapping the IC switch voltage to the input in the circuit of Figure 1 improves efficiency by about 3%. Of course, the FET actively turns on when the source goes low. But simply using ...
