The LT1374IR-SYNC is a 500kHz step-down switching regulator manufactured by LT. It integrates a 4.5A switch, oscillator, control, and logic circuitry on a single die. This device operates at a constant 500kHz switching frequency, allowing for a reduction in the size of external components.
The regulator utilizes a current mode topology for fast transient response and good loop stability. It includes features such as cycle-by-cycle current limiting and thermal shutdown protection. The device is available in a 16-pin TSSOP package and supports surface mount components.
Key electrical specifications include an effective supply current of 2.5mA and a shutdown current of 20µA. The input voltage range is up to 25V, with a BOOST pin voltage rating of 38V. The saturating switch design offers a low on-resistance of 0.07Ω.
Applications for the LT1374IR-SYNC include portable computers, battery-powered systems, battery chargers, and distributed power systems.
