Product Overview

The LT1777IS#PBF is a Buck/Step-down Regulator designed for noise sensitive applications. It contains a dI/dt limiting circuit programmed via a small external inductor in the switching path. Internal circuitry also generates controlled dV/dt ramp rates. The monolithic die includes all oscillator, control and protection circuitry. The part can accept operating input voltages as high as 48V and contains an output switch rated at 700mA peak current. Current-mode control offers excellent dynamic input supply rejection and short-circuit protection. The internal control circuitry is normally powered via the VCC pin, thereby minimizing power drawn directly from the VIN supply.
  • Programmable dI/dt limit
  • Internally limited dV/dt
  • True current mode control
  • Synchronizable to 250kHz
  • 100kHz Fixed operating frequency
  • 30µA Low supply current in shutdown
