... The typical input bias current of the OPA378 during normal operation is approximately 150pA. In over-driven conditions, the bias current can increase significantly (see Figure 24). The most common cause of an over-driven condition occurs when the op amp is outside of the linear range of operation. W ...

Buck converter



A buck converter is a voltage step down and current step up converter.The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12V in a desktop, 12-24V in a laptop) down to the 0.8-1.8V needed by the processor.
