LT3682 1A Micropower Step-Down Switching Regulator FEATURES n DESCRIPTION The LT®3682 is an adjustable frequency (250kHz to 2.2MHz) monolithic buck switching regulator that accepts input voltages up to 36V. A high efficiency 0.5Ω switch is included on the device along with 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 Low Ripple Burst Mode maintains high efficiency at low output currents while keeping output ripple below 15mV in typical applications.
