LT8610A/LT8610AB Series
42V, 3.5A Synchronous
Step-Down Regulator with
2.5µA Quiescent Current
FEATURES
n
DESCRIPTION
The
LT
®
8610A/LT8610AB
series are compact, high ef-
ficiency, high speed synchronous monolithic step-down
switching regulators that consume only 2.5µA of quies-
cent 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 synchroni-
zation 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.
