Abstract
A pulse generator for generating the pulses setting an on-time utilized for switching a DC-DC converter includes a voltage divider having a tap at which a dithered reference voltage is produced, a voltage to current converter arrangement generating a charging current having a magnitude based upon the dithered reference voltage, a timing capacitor that is charged by the charging current, a reset switch for the timing capacitor, and a comparator generating a pulse based on a comparison between a timing voltage stored on the timing capacitor and a reference voltage, with a width of the pulse being set as a function of a rate of the charging of the timing capacitor by the charging current. The voltage divider is adjustable and incrementally changes a resistance seen at the tap of the voltage divider so that the dithered reference voltage is modulated in a stair-stepped triangular fashion.
