The LT ® LT8610EMSE#TRPBF
8610 is a compact, high efficiency, high speed
synchronous monolithic step-down switching regulator
that 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 10mV P-P. A SYNC pin allows synchronization
to an external clock. Internal compensation with peak cur-
rent mode topology allows the use of small inductors and
results in fast transient response and good loop stability.
The EN/UV pin has an accurate 1V threshold and can be
used to program V IN undervoltage lockout or to shut down
the LT8610 reducing the input supply current to 1μA. A
capacitor on the TR/SS pin programs the output voltage
ramp rate during start-up. The PG flag signals when VOUT
is within ±9% of the programmed output voltage as well
as fault conditions. The LT8610 is available in a small
16-lead MSOP package with exposed pad for low thermal
resistance. LT8610EMSE#TRPBF
