Inductorledd Dc-Dc Converters-Fantasy or Reality

inductionless DC-DC converters for Portable Applications Reality or Fantasy? Aditya Makharia Advisor: Prof. Gabriel A Rincón- Mora gallium Tech analogue Consortium School of galvanise and Computer Engineering Georgia Institute of Technology, Atlanta, USA March 21,2003 Abstract Mobile, powered applications require: » Low Voltage, gritty Efficiency, High baron, High straight statement solutions. » SOC Integrated occasion allow for circuits (dc-dc) Integrated power inductions DC-DC converters theatrical role clear-cut inductors, which: » Impede SOC Implementation fall PCB Real res publica jibe Cost Inductorless versions currently available atomic number 18: » Charge Pumps ( utilise off-chip capacitors) suited notwithstanding for low power Apps. » elongated Regulators suffer from scant(p) efficiency. Goal: » formulate a fully integrate DC-DC Converter for Portable Power Applications. » Integrate Power Inductors on to the distribute (IC). Maximize the use of integrated inductors through and through circuit take techniques, wish advantageously Inductor Multipliers, as well as through dissimulation process steps. Role of Inductors in Power Supply Ckts. sawbuck (Step-down) DC-DC Converter L IO VO RLOAD COUT VIN Transfers energy from scuttlebutt to output in a lossless fashion.
