LTC1435A High Efficiency Low Noise Synchronous Step-Down Switching Regulator FEATURES s s s s DESCRIPTION The LTC®1435A is a synchronous step-down switching regulator controller that drives external N-channel power MOSFETs using a fixed frequency architecture. A wide duty cycle range of 5% to 99% allows high VIN to low VOUT DC/DC conversion, as well as low dropout operation that extends operating time in battery-operated systems. Burst ModeTM operation provides high efficiency at low load currents. The operating frequency is set by an external capacitor allowing maximum flexibility in optimizing efficiency. A secondary winding feedback control pin, SFB, guarantees regulation regardless of load on the main output by forcing continuous operation.
