3.3V Lithium Cell Supply Requires One Inductor:
08/05/99 EDN Design Ideas / (added10/05) Because of growing popularity of lithium-ion (Li-ion) batteries and 3.3V power supplies, portable-equipment designers must often create a
3.3V supply that a single Li-ion cell can power. fact that output of a Li-ion battery ranges above and below 3.3V during its discharge cycle complicates design.
AN26 Fast Charging Batteries with Zetex High Current PNP Transistors and Benchmarq Controller ICs: Zetec Semiconductors
Applications Notes High current, fast switching PNP transistors are capable of replacing large packaged P-Channel MOSFETs, when attention is paid to base drive requirements. This enables
space and performance efficient designs at much reduced cost. (app note added 6/06)
AN40 Lithium Ion Battery Charging using Bipolar Transistors: Zetec Semiconductors Applications Notes This application
note explores different types of charge techniques and associated discrete pass elements, highlighting dominant discrete parameters and selection criteria for each charging
technique. (app note added 2/06)
