Description

The LT3693 is an adjustable frequency (200kHz to 2.4MHz) monolithic buck switching regulator that accepts input voltages up to 36V. A high efficiency 95mΩswitch is included on the die along with a boost Schottky diode and the necessary oscillator, control, and logic circuitry. Current mode topology is used for fast transient response and good loop stability. Shutdown reduces input supply current to less than 1µA while a resistor and capacitor on the RUN/SS pin provide a controlled output voltage ramp (soft-start). A power good ag signals when VOUT reaches 91% of the programmed output voltage. The LT3693 is available in 10-Pin MSOP and 3mm x 3mm DFN packages with exposed pads for low thermal resistance.
