Product Summary

The LT1767EMS8E-5 is a 1.25MHz monolithic buck switching regulator. A high efficiency 1.5A, 0.22Ω switch is included on the die together with all the control circuitry required to complete a high frequency, current mode switching regulator. The LT1767EMS8E-5 is available in an 8-pin MSOP fused leadframe package and a low thermal resistance exposed pad package. New design techniques achieve high efficiency at high switching frequencies over a wide operating range. The applications of the LT1767EMS8E-5 are DSL Modems, Portable Computers, Wall Adapters, Battery-Powered Systems, Distributed Power.
