LT3695 switching regulator

The LT3695 is an adjustable frequency (250kHz to 2.2MHz) monolithic buck switching regulator designed in a small package . LT3695 buck switching regulator operates over a wide input voltage range from 3.6V to 36V and can safely sustain transient voltages up to 60V.

A SYNC pin allows the user to synchronize the part to an external clock, and to choose between low ripple Burst Mode operation and standard PWM operation.

Output voltage range that can obtained using the LT3695 switching regulator is form 0.8V to 20V with a maximum output current of 1 Amp .

The output voltage of the LT3695 regulator  is programmed with a resistor divider between the output and the FB pin. The resistor value can be calculate using these formula :
