Product Details

The LT8620 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that accepts a wide input voltage range up to 65V, and consumes only 2.5μA of quiescent current. Top and bottom power switches are included with all necessary circuitry to minimize the need for external components. Low ripple Burst Mode operation enables high efficiency down to very low output currents while keeping the output ripple below 10mVP-P. A SYNC pin allows synchronization to an external clock.

Ultralow Quiescent Current Burst Mode Operation
Output Ripple < 10mVP-P
High Efficiency Synchronous Operation
Fast 30ns Minimum Switch-On Time
Low Dropout Under All Conditions: 250mV at 1A
Safely Tolerates Inductor Saturation in Overload
Low EMI
Accurate 1V Enable Pin Threshold
Internal Compensation
Output Soft-Start and Tracking
