The primary power source uses the internal linear regulator to provide the output voltage. When the primary power source is removed, the secondary power source is stepped up using the internal switching regulator to provide the output voltage. 7.2 Functional Block Diagram 7.3 Feature Description The TL499A has an adjustable output voltage set by feedback provided to REF pin abs an adjustable switching current is set by value of resistor on SW CURRENT CONTROL pin. The lower resistance provides increased switching current. Dual power supply inputs also provide protection against power faults on the main supply of the TL499A. 7.4 Device Functional Modes The TL499A has two functional modes: • Linear voltage regulation when SERIES IN1 supply is present. • Step-up voltage regulation when SERIES IN1 supply is absent. 6 Submit Documentation Feedback Copyright © 1984–2015, Texas Instruments Incorporated Product Folder Links: TL499A |
