The LT1765ES8#PBF is a monolithic 3A, 1.25MHz step-down switching regulator manufactured by Linear Technology. This device integrates a high efficiency 3A, 0.09Ω switch along with control circuitry for a high-frequency, current mode switching regulator. Its current mode control ensures fast transient response and excellent loop stability.
Designed for a wide operating voltage range from 3V to 25V, the LT1765ES8#PBF is suitable for various applications including DSL modems, portable computers, regulated wall adapters, battery-powered systems, and distributed power. It features a constant 1.25MHz switching frequency, which allows for the use of low-profile surface mount components and chip inductors, reducing overall solution size.
Key electrical characteristics include a 1.2V feedback reference voltage and a low shutdown current of 15μA, which helps improve efficiency at lower output currents. The regulator also offers synchronization capability up to 2MHz and provides full cycle-by-cycle current control and thermal shutdown for protection.
The LT1765ES8#PBF is available in an 8-Lead SO package and a 16-Lead Thermally Enhanced TSSOP package, both designed for surface mounting.
The maximum input voltage for the LT1765ES8#PBF is 25V.
The LT1765ES8#PBF has a constant switching frequency of 1.25MHz.
The LT1765ES8#PBF features a typical switch current rating of 3A.
The LT1765ES8#PBF is available in an 8-Lead SO package and a 16-Lead Thermally Enhanced TSSOP package.
The shutdown current for the LT1765ES8#PBF is a low 15μA.
