Product Overview

The LT1961IMS8E#PBF is a monolithic boost Switching Regulator for use with DSL modems. A high efficiency 1.5A, 0.2R 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 voltage 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 maintains high 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 1.5 to 2MHz. Full cycle-by-cycle switch current limit protection and thermal shutdown is provided.
  • Uses low profile surface mount external components
  • Current-mode loop control
  • Constant maximum switch current rating at all duty cycles
  • ±2% Overall output voltage tolerance
  • 6µA Low shutdown current
