1 / 24 page  1 LT1777 Low Noise Step-Down Switching Regulator s Programmable dI/dt Limit s Internally Limited dV/dt s High Input Voltage: 48V Max s 700mA Peak Switch Rating s True Current Mode Control s 100kHz Fixed Operating Frequency s Synchronizable to 250kHz s Low Supply Current in Shutdown: 30 µA s Low Thermal Resistance 16-Pin SO Package 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. 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 pow- ered via the VCC pin, thereby minimizing power drawn directly from the VIN supply (see Applications Informa- tion). The fused-lead SO16 package and 100kHz switch- ing frequency allow for minimal PC board area requirements.
