Product Overview

The LT1767EMS8E#PBF is a monolithic buck Switching Regulator for use with DSL modems. A high efficiency 1.5A, 0.22R switch is included on the die together with all the control circuitry required to complete a high frequency, current mode switching regulator. Current-mode control provides fast transient response and excellent loop stability. New design techniques achieve high efficiency at high switching frequencies over a wide operating range. A low dropout internal regulator maintains consistent performance over a wide range of inputs from 24V systems to Li-ion batteries. An operating supply current of 1mA improves efficiency, especially at lower output current. Shutdown reduces quiescent current to 6µA. Maximum switch current remains constant at all duty cycles. Synchronization allows an external logic level signal to increase the internal oscillator from 1.5 to 2MHz. Full cycle-by-cycle current limit and thermal shutdown is provided.
  • Uses low profile surface mount components
  • Current-mode loop control
  • Constant maximum switch current rating at all duty cycles
  • Synchronizable to 2MHz
  • 2% Overall output tolerance
