The TL499ACPSR from Texas Instruments is an integrated circuit designed as a wide-range power-supply controller. It functions as a step-up (boost) switching regulator, providing an adjustable output voltage that can be set from 2.9V to 30V using two external resistors. The device operates with an input voltage range of 1.1V to 10V for the switching regulator.
Key electrical characteristics include a maximum output current of 1A (switch), a maximum duty cycle of 70%, and a typical quiescent current of 0.0008A. The operating temperature range is -20°C to 85°C.
This controller is suitable for applications requiring adjustable regulated supply voltages. It can operate as a series DC voltage regulator when AC-coupled to line power through a step-down transformer. With the addition of external components like an inductor and capacitors, it can function as a step-up switching regulator, providing backup power during AC-line failures.
The TL499ACPSR is available in an 8-SOIC surface-mount package.
