LT1374IR-5#TRPBF Description

Short technical summary and product information.

The LT1374IR-5#TRPBF is a 500kHz monolithic buck mode switching regulator manufactured by LT. It integrates a 4.5A switch along with essential oscillator, control, and logic circuitry. This high switching frequency enables a significant reduction in the size of external components, making it suitable for space-constrained applications.

 

The regulator utilizes current mode topology for fast transient response and good loop stability. Key electrical specifications include a typical supply current of 2.5mA and a shutdown current of 20µA. The design also allows for reduced inductor size, down to 1.8µH, and features a saturating switch design with an effective resistance of 0.07Ω.

 

Available in various packages including TSSOP-16, DDPAK-7, SO-8, and TO-220, the LT1374IR-5#TRPBF is designed for surface mount components. Both fixed output voltage and adjustable versions are available, offering design flexibility.
