PPT-Integration Aspects of DC-DC Converters

TUPO June 10 th 2009 Katja Klein 1 Physikalisches Institut B RWTH Aachen University Outline Katja Klein 2 Conversion ratio amp output current Dimensions and weight of buck converters. DACs are most easily understood by examining a simplified DAC block diagram As shown in Figure 1 the architecture of a onechannel DAC consists of a resistor array each of equal value R followed by a railtorail voltage output amplifier The voltage a 114 AD Converters ADCs perform two basic fundamental operations discretiza tion in time and discretization in amplitude e two functions are shown con ceptually in Figure 1 though the actual ADCmay not be structure as such 1 e rst operation of the These operating ranges may be broad and in some cases may overlap It is usually not possible to derive any arbitrary output voltage from the entire range of permissible input voltages There are several factors that can cause this including the inter Power Options preinstalled ATPWR4 power supply powers the ATMCR12 eliminating the need for multiple po wer connections Allied Telesis also offers an optional hot swappable power supply to eliminate do wntime on the netw or kThe unit saves space in t A new family of complementary MOS multiplying digitaltoanalog converters has arrived on the scene and promises to make microprocessor interfacing truly universal The doublebuffered MICRODAC units eliminate many common problems bridging the way to a 373.
