LT1376CS8#TR

The LT1376CS8#TR is a 500kHz monolithic buck mode switching regulator manufactured by LT. It integrates a 1.5A switch along with necessary oscillator, control, and logic circuitry. This high switching frequency allows for a significant reduction in the size of external components, making it suitable for space-constrained applications.

The regulator utilizes a current mode topology for fast transient response and good loop stability. It is available in both fixed output voltage and adjustable versions. The design employs a special high-speed bipolar process and new techniques to achieve high efficiency, even at high switching frequencies. Efficiency is maintained across a wide output current range.

Key electrical specifications include a typical supply current of 2.5mA and a shutdown current of 20µA. The switch has a saturating design with a typical resistance of 0.4 ohms. The LT1375/LT1376 series fits into standard 8-pin PDIP and SO packages, as well as a 16-pin SO package with lower thermal resistance. This specific part, LT1376CS8#TR, is supplied in an 8-pin SOIC package and is configured for tape and reel mounting.

Features such as full cycle-by-cycle short-circuit protection and thermal shutdown are provided for reliability. Standard surface mount external components, including the inductor and capacitors, are used in its implementation. This makes it a versatile component for applications like portable computers, battery-powered systems, battery chargers, and distributed power systems.
