The LT1374CS8-SYNC is a high-efficiency, 500kHz step-down switching regulator manufactured by Linear Technology. Designed for space-constrained applications, it integrates a 4.5A power switch with a saturating switch design that minimizes on-resistance to 0.07Ω. The constant 500kHz switching frequency significantly reduces the required size of external passive components, such as inductors and capacitors. This device operates from an input voltage range up to 25V and features cycle-by-cycle current limiting and thermal shutdown protection for robust operation.
Key design advantages include an effective supply current of just 2.5mA and a deep sleep mode drawing only 20µA when the shutdown pin is activated. The SYNC variant supports external synchronization, allowing the internal oscillator to be adjusted between 580kHz and 1MHz using a logic-level signal. Packaged in a compact 16-pin TSSOP with an exposed pad for enhanced thermal performance, it utilizes all surface-mount components for streamlined PCB assembly.
