ABSTRACT:
A programmable DC-DC converter controller with a high speed synchronous controller and a 5-bit programmable DAC provides an operating voltage to an external device (such as a microprocessor) in response to a 5 bit code programmed in the external device. The 5-bit programmable DAC outputs a signal which provides voltages to the external device in increments of e.g. 50 or 100 millivolts, in respectively two different voltage ranges.
