LT1374CT7-5#PBF

The LT1374CT7-5#PBF is a 4.5A, 500kHz step-down switching regulator manufactured by Linear Technology. Designed for high-efficiency power conversion, this monolithic buck converter integrates a 4.5A power switch along with all necessary oscillator, control, and logic circuitry on a single die. The fixed 500kHz switching frequency allows designers to significantly reduce the size of external passive components, including inductors as small as 1.8µH.

Operating in current mode topology, the device provides rapid transient response and excellent loop stability under varying load conditions. Key electrical characteristics include an effective on-resistance of just 0.07Ω, a typical supply current of 2.5mA, and a low shutdown current of 20µA for enhanced power management in standby modes. The adjustable output voltage configuration offers flexibility for various system requirements.

Housed in a robust TO-220 through-hole package, the LT1374CT7-5#PBF is well-suited for applications requiring reliable thermal performance and straightforward PCB mounting. It is commonly utilized in industrial equipment, telecommunications infrastructure, and embedded systems where compact, efficient DC-DC conversion is critical. Engineers can rely on its consistent performance across standard operating temperature ranges while benefiting from simplified design cycles due to integrated protection features.
