LT1076CT#30PBF

The LT1076CT#30PBF is a versatile step-down switching regulator manufactured by Analog Devices (formerly Linear Technology). This component is designed for efficient power conversion, utilizing a classic positive buck configuration. Its topology allows for flexibility, enabling its use as a positive-to-negative converter, a negative boost converter, and a flyback converter.

Key electrical specifications include an onboard switch with a 5A rating and an impressive input voltage capability of up to 60V. It operates at a switching frequency of 100kHz, offering a good balance between efficiency and component size. The quiescent current is a low 8.5mA, making it suitable for power-sensitive applications. The device also features a programmable current limit and a micropower shutdown mode.

This regulator is available in a low-cost 5-lead TO-220 package, suitable for through-hole mounting. The design innovations contribute to greatly improved dynamic behavior. The switch output is specified to swing 40V below ground, which is a notable feature for certain converter topologies.

Applications for the LT1076CT#30PBF include various DC-DC conversion tasks where a robust and flexible switching regulator is required. Its high input voltage capability and onboard switch simplify circuit design and reduce component count.
