ANALOG DEVICES LT3695EMSE-5#PBF DC-DC Switching Buck Regulator, Fixed, 3.6 to 36V in, 5V / 1A Out, MSOP-16

LT3695EMSE-5#PBF is LT®3695 series adjustable frequency (250KHz to 2.2MHz) monolithic buck switching regulator capable of accepting input voltages up to 36V and safely sustaining transient voltages up to 60V. This device integrates a high-efficiency switch, a boost diode, and all necessary oscillator, control, and logic circuitry. Utilizing current mode topology ensures fast transient response and good loop stability. With a SYNC pin, users can synchronize the regulator to an external clock and choose between low ripple Burst Mode operation and standard PWM operation. It features tolerance to 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 typical applications. Applications include automotive battery regulation, automotive entertainment systems, distributed supply regulation, industrial supplies.
