Description

The LTC?435A 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 VOUTDC/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 of LTC1435A 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. Burst Mode operation is inhibited when the SFB pin is pulled low, which reduces noise and RF interference.

Soft start is provided by an external capacitor that can be used to properly sequence supplies. The operating current level is user-programmable via an external current sense resistor.Wide input supply range of LTC1435A allows operation from 3.5V to 30V (36V maximum).
