DESCRIPTION
The LT®3973 is an adjustable frequency monolithic buck switchingregulatorthatacceptsawideinputvoltagerange up to 42V, and consumes only 2.5µA of quiescent current. A high efficiency switch is included on the die along with the catch diode, boost diode, and the necessary oscillator, control and logic circuitry. Low ripple Burst Mode operation maintains high efficiency at low output current swhile keeping the output ripple below 10mV in a typical application.
