This article reviews a technique to bootstrap a power supply that only dissipates power during startup and makes it easier to meet these new green-mode specifications.

The circuit in Figure 1 takes advantage of the 1.8-V power supply to provide a delayed Enable for the 3.3-V MOSFET. Synchronous buck controllers use a bootstrap circuit to drive the high-side MOSFET.

Many single supply powered applications require amplifier output swings within millivolt or even sub-millivolt levels of ground. Amplifier output saturation limitations normally preclude such ...

You can also choose operating voltages or solenoid specifications that result in lower continuous current through the solenoid, reducing dc power consumption and resulting in a cooler-running solenoid ...
