Abstract
In an example, a voltage converter includes a pulse generator. The voltage converter also includes a high-side transistor having a gate coupled to the pulse generator, a source coupled to a first voltage terminal, and a drain coupled to an output node. The voltage converter includes a low-side transistor having a gate coupled to the pulse generator, a source coupled to a second voltage terminal, and a drain coupled to the output node. The voltage converter includes a charge lookup table coupled to the pulse generator, where the charge lookup table is configured to provide a charge duration. The voltage converter includes a discharge lookup table coupled to the pulse generator, where the discharge lookup table is configured to provide a discharge duration. The voltage converter also includes a latch coupled to the charge lookup table, where the latch is configured to store an indication of a supply voltage.
