The LT8610A/LT8610AB series are compact, high efficiency, high speed synchronous monolithic step-down switching regulators that consume only 2.5μA of quiescent current. Compared to the LT8610, they have higher maximum output currents of 3.5A and a faster minimum switch-on time of 30ns. The LT8610A has the same low ripple burst mode performance of the LT8610, while the LT8610AB has even higher light load efficiency.

The other features of the LT8610 remain unchanged in the LT8610A/LT8610AB series. A SYNC pin allows synchronization to an external clock. The EN/UV pin has an accurate 1V threshold for V_IN undervoltage lockout or shut down. A capacitor on the TR/SS pin programs the output voltage ramp rate during startup. The PG flag signals when V_OUT is within ±9% of the programmed output voltage as well as fault conditions.

Product Details

Demonstration circuit 2139A is a 42V, 3.5A micropower synchronous step-down regulator featuring the LT8610A. The LT8610A is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that consumes only 2.5μA of quiescent current when output is regulated at 5V and is unloaded. The 2139A uses two input ceramic capacitors in series to improve reliability in case of an input capacitor short failure. Top and bottom power switches, compensation components and other necessary circuits are inside of the LT8610A to minimize external components and simplify design.

Product Details

Demonstration circuit 2012A is a 42V, 3.5A micropower synchronous step-down regulator featuring the LT8610AB. The LT8610AB is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that consumes only 2.5μA of quiescent current when output is regulated at 5V. The efficiency of the circuit is greater than 90% at light load up to 1.5A. This is a 10% improvement over competing parts. Top and bottom power switches, compensation components and other necessary circuits are inside of the LT8610AB to minimize external components and simplify design.
