THEORY OF OPERATION The ADP1073 is a flexible, low power switch mode power supply (SMPS) controller. The regulated output voltage can be greater than the input voltage (boost or step-up mode) or less than the input (buck or step-down mode). ...

ADP1073 COMPONENT SELECTION General Notes on Inductor Selection When the ADP1073 internal power switch turns on, current begins to flow in the inductor. Energy is stored in the inductor core while the switch is on, and this stored energy is ...

ADP1073 Capacitor Selection For optimum performance, the ADP1073’s output capacitor must be carefully selected. Choosing an inappropriate capacitor can result in low efficiency and/or high output ripple. Ordinary aluminum electrolytic capacitors are inexpensive, but often have poor Equivalent Series Resistance ...
