The THX3039 with Switching Controllers DIP-7 RoHS manufactured by THX is a switching regulator integrated circuit (IC) designed for switching power supplies. It is comprised of a control circuit, switching and driver transistors, and frequency compensation components housed in a 7-pin DIP package. This IC offers a wide input voltage range, low ripple, and fast transient response performance, making it suitable for use in adjustable and switch mode power supplies. It operates with a frequency range of 100 kHz to 300 kHz for adjustable or switch mode power supplies, and has a wide range of protection features including thermal shutdown, output short circuit protection, over current protection, and protection against reversed polarity. The integrated circuit is RoHS compliant and comes in a surface-mount package.
