Description

The SC410A is an integrated, synchronous 2A 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 7V to 24V with a

programmable output voltage from 0.75V up to 7.5V. The

device features an internal LDO and 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, output OV protection and over temperature

protection. The open-drain PGOOD pin provides output

status.

The device is available in a low profile, thermally enhanced

MLPD 3 x 3(mm) 10-pin package.
