LT3695EMSE#PBF

LT3695EMSE#PBF is an adjustable frequency (250KHz to 2.2MHz) monolithic buck switching regulator that accept input voltages upto 36V and can safely sustain transient voltages upto 60V. This device includes a high efficiency switch, a boost diode, and the necessary oscillator, control and logic circuitry. Current mode topology is used for fast transient response and good loop stability. 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. The LT3695 regulators tolerates adjacent pin shorts or an open pin without raising the output voltage above its programmed value. Low ripple Burst Mode operation maintains high efficiency at low output currents while keeping output ripple below 15mV in a typical application. It is used in application such as automotive battery regulation, automotive entertainment systems, distributed supply regulation, industrial supplies etc.
