Power Converter CircuitsAbhiman HandeResearch AssociateSlide Acknowledgements: Siamak Abedinpour, Freescale Semiconductor Inc.April 26, 2006Embedded and Adaptive AAH, April 2006TMZigBee Alliance | Wireless Control That Simply WorksComputing GroupLow Dropout (LDO) Linear Regulator Vout must be less than Vin MOSFET pass device allows low dropout voltage. No inductance required, and small simple circuit. No switching noise, and good power supply rejection ratio (PSRR)performance. Application: suitable for analog base-band, and RF blocks.Embedded and Adaptive AAH, April 2006TMZigBee Alliance | Wireless Control That Simply WorksComputing GroupSwitched-Capacitor (SC) DC-DC Converter M is fixed by the topology and is used to bring Vout close to the desired value. Application: Suitable to supply the display, which is of great importance in next generation handsets.Embedded and Adaptive AAH, April 2006TMZigBee Alliance | Wireless Control That Simply WorksComputing GroupStep-Down SC DC-DC ConverterEmbedded and Adaptive AAH, April 2006TMZigBee Alliance | Wireless Control That Simply WorksComputing GroupStep-Up SC DC-DC ConverterEmbedded and Adaptive AAH, April 2006TMZigBee Alliance | Wireless Control That Simply WorksComputing GroupClosed Loop Control M is fixed by the topology and is used to bring Vout close to the desired value. A control circuit could adjust the switching frequency to regulate Vout. Efficiently convert ...
