TL499ACP Description

Short technical summary and product information.

The TL499ACP is an integrated circuit from Texas Instruments designed as a wide-range power-supply controller. It functions as a step-up (boost) switching regulator, capable of providing adjustable regulated output voltages from 2.9 V to 30 V. The output voltage can be precisely set using two external resistors.

 

This device operates with an input voltage range suitable for various power sources. Key electrical characteristics include a switch current of 1A, a maximum duty cycle of 70%, and a low typical quiescent current of 0.0008A. The operating temperature range is specified from -20°C to 85°C.

 

The TL499ACP is housed in an 8-pin DIP package and supports through-hole mounting. Its design allows for externally controlled switching current and does not require an external rectifier. This makes it suitable for applications requiring flexible and adjustable power supply solutions, including backup power during AC-line failures when configured with a battery and associated components.
