The LT1765ES8#PBF is a monolithic 3A, 1.25MHz step-down switching regulator from ADI Electronics. It integrates a high efficiency 3A, 0.09Ω switch along with control circuitry for a high frequency, current mode switching regulator. Current mode control ensures fast transient response and excellent loop stability.
This regulator features a wide operating voltage range from 3V to 25V, making it suitable for various power systems including 24V systems and Li-Ion batteries. It maintains consistent performance with a low dropout internal regulator. The device operates with a supply current of 1mA, improving efficiency at lower output currents, and reduces quiescent current to 15μA in shutdown mode.
Key electrical characteristics include a constant 1.25MHz switching frequency, a 1.2V feedback reference voltage, and synchronizability up to 2MHz. The LT1765ES8#PBF is available in 8-Lead SO and 16-Lead Thermally Enhanced TSSOP packages, designed for surface mount applications using low profile components.
Applications for this switching regulator include DSL modems, portable computers, regulated wall adapters, battery-powered systems, and distributed power systems. Its high frequency operation allows for smaller input and output filtering components, including chip inductors.
