TL499A Datasheet (Texas Instruments) - Wide-Range Power-Supply Controllers

TL499A, Wide-Range Power-Supply Controllers

The TL499A device is an integrated circuit designed to provide a wide range of adjustable regulated supply voltages.

The regulated output voltage can be varied from 2.9 V to 30 V by adjusting two external resistors.

When the TL499A is ac-coupled to line power through a step-down transformer, it oper
