■ DESCRIPTIO The LT ®1777 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. Programmable dI/dt Limit
Internally Limited dV/dt
High Input Voltage: 48V Max
700mA Peak Switch Rating
True Current Mode Control
100kHz Fixed Operating Frequency
Synchronizable to 250kHz
Low Supply Current in Shutdown: 30µA …
