Description
The SC402B is a stand-alone synchronous EcoSpeed
?/DIV>
buck
power supply which incorporates Semtechs advanced
patented adaptive on-time control architecture. This pro-
vides excellent light-load efficiency and fast transient
response. It features integrated power MOSFETs, a boot-
strap switch, and a programmable LDO in a 5x5mm
package. The device is highly efficient and uses minimal
PCB area. The SC402B has the same package and pin con-
fguration as the entire SC40x series for compatibility.
The SC402B supports using standard capacitor types such
as electrolytic or specialty polymer, in addition to ceramic,
at switching frequencies up to 1MHz. The programmable
frequency, synchronous operation, and selectable power-
save provide high efficiency operation over a wide load
range.
Additional features include a programmable soft-start,
programmable cycle-by-cycle over-current limit protec-
tion, under-voltage and over-voltage protection, soft
shutdown, and selectable power-save operation. The
device also provides separate enable inputs for the PWM
controller and LDO as well as a power good output for the
PWM controller.
The wide input and programmable frequency make the
device extremely flexible and easy to use in a broad range
of applications.
