The regulated output voltage can be • Output Adjustable From 2.9 V to 30 V varied from 2.9 V to 30 V by adjusting two external • 1-V to 10-V Input for Switching Regulator resistors. When the TL499A is ac-coupled to line power through a step-down transformer, it operates • 4.5-V to 32-V Input for Series Regulator as a series DC voltage regulator to maintain the • Externally Controlled Switching Current regulated output voltage. With the addition of a • No External Rectifier Required battery from 1.1 V to 10 V, an inductor, a filter capacitor, and two resistors, the TL499A operates as 2 Applications a step-up switching regulator during an AC-line failure. The adjustable regulated output voltage • Voltage Boosting makes the TL499A useful for a wide range of • Dual-Supply Voltage Reglation applications. Providing backup power during an AC- line failure makes the TL499A extremely useful in • Battery Back-Ups microprocessor memory applications. The TL499AC • Microprocessor Memory Power is characterized for operation from –20°C to +85°C.
