Abstract
An monolithic programmable dc--dc converter controller integrated circuit with a high speed synchronous controller and a 4-bit programmable DAC to provide an operating voltage to an external device such as a microprocessor in response to a code programmed in the external device. The 4-bit programmable DAC outputs a signal which is combined with a precise reference voltage to provide voltages to the external device in increments of 100 millivolts.
