Product Overview

The LT1765ES8#PBF is a monolithic 1.25MHz step-down Switching Regulator ideal for DSL modems. A high efficiency 3A, 0.09R switch is included on the die together with all the control circuitry required to construct 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 LDO 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. Maximum switch current remains constant at all duty cycles. Synchronization allows an external logic level signal to increase the internal oscillator into the range of 1.6 to 2MHz. High frequency operation allows the reduction of input and output filtering components and permits the use of chip inductors.
