The SC410 is an integrated, synchronous 3A EcoSpeed ?
step-down regulator. It incorporates Semtech’s advanced,
patented adaptive on-time architecture to achieve best-
in-class dynamic performance using point-of-load appli-
cations. The input voltage range is 5.5V to 24V with a
programmable output voltage from 0.75V up to 7.5V. The
device features an internal LDO and ultrasonic PSAVE
mode for high efficiency across the output load range.
Adaptive on-time control provides programmable
pseudo-fixed frequency operation in continuous conduc-
tion and excellent transient performance. The switching
frequency can be set from 200kHz to 1MHz, allowing the
designer to reduce external LC filtering and minimize light
load (standby) losses.
Additional features include cycle-by-cycle current limit,
soft start, input UVLO and output OV protection, and over
temperature protection. The open-drain PGOOD pin pro-
vides output status. Standby current is less than 10μA
