Switch-mode Power Converter
Employing a switch-mode power converter. Another
approach to transferring the battery energy to the system
load is to employ a switch-mode power converter. The
primary advantage of a switch-mode power converter is that
it can, ideally, accomplish power conversion and regulation
at 100% efficiency. All power loss is due to non-ideal
components and power loss in the control circuit.
The buck converter is an inductor based switch-mode power
converter used to step-down an input source to a lower
magnitude output. The buck converter goes by many names:
voltage step-down converter, DC-to-DC converter, chopper
converter, etc. No matter what the name, inductor based,
buck derived, switch-mode converters account for 80% to
90% of all converters sold.
Microchip offers inductor based buck regulators and
controllers. The distinction is whether or not the switch
(MOSFET) is internal to the device (regulator) or controlled
externally (controller). The schematic represented here
depicts a MCP1601 buck regulator with its associated
external components.
