Abstract
The systems and methods of auto-configurable switching/linear regulation disclosed herein enable a device to operate in both DC-to-DC switching regulation and linear regulation applications. The systems and methods disclosed herein differentiate between switching and linear mode. If the application is for a linear regulator, there will only be a capacitor on the output. If the application is for switching mode regulation, there will be an inductor and a capacitor on the output. Then based on the determination, the mode is selected and the hardware is converted into switching regulator operation or linear regulator operation.
Claims20
A system comprising:
- a DC-DC converter comprising:
- a comparator/error amplifier;
- a logic module;
- a high-side driver;
- and
- a low-side driver,
- the logic module configured to switch between the high-side driver and the low-side driver in switching mode and configured to only drive the high-side driver or the low-side driver in linear mode.
A method comprising:
- selecting between switching mode and linear mode for a DC-DC converter, the DC-DC converter comprising a high-side driver and a low-side driver, switching mode further comprising alternatively switching the high-side driver and the low-side driver, linear mode further comprising only driving the high-side driver.
A system comprising:
- means for selecting between switching mode and linear mode for a DC-DC converter, the DC-DC converter comprising a high-side driver and a low-side driver, switching mode further comprising alternatively switching the high-side driver and the low-side driver, linear mode further comprising only driving either the high-side driver or the low-side driver.
