Product Overview

The LT1767EMS8E-3.3#PBF is an 1.25MHz monolithic buck Switching Regulator with 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. 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 currents. 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 1.5MHz to 2MHz.
  • Uses low profile surface mount components
  • Synchronizable to 2MHz
  • Current mode loop control
  • Constant maximum switch current rating at all duty cycles
  • 2% Overall output tolerance
  • 1.2V Feedback reference voltage
  • 6µA Low shutdown current
  • 2% Overall output tolerance
