LT1777 Low Noise Step-Down Switching Regulator FEATURES s s s s s s s s s DESCRIPTIO 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 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.
