A Boost converter is a switch-mode power supply that uses switching and control to increase the DC voltage of a rail. Specifically a Boost regulator works with an inductor with one terminal attached to VIN and the other attached to a low side FET. This FET switches on shorting the inductor to ground, due to the inductance, current begins to ramp and a magnetic field is formed in the inductor. Once this field is sufficient, the fet turns off and the energy stored in the inductor magnetic field is discharged through a diode into a capacitor. This diode (also known as the rectification diode) also has the purpose of blocking leakage of this capacitor.
Triad has a variety of power management IP including Boost Converters. We also work with customers to create custom and specialized boost converters that are specifically designed for certain input or load characteristics.
