Description
The SC417/SC427 is a stand-alone synchronous
EcoSpeed
TM
buck regulator which incorporates Semtechs
advanced, patented adaptive on-time control architecture
to provide 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
15x20mm PCB area for a total converter solution. Refer to
page 16 for information on the C-SIM simulation tool.
The SC417/SC427 supports using standard capacitor types
such as electrolytic or special polymer, in addition to
ceramic, at switching frequencies up to 1MHz. The pro-
grammable frequency, synchronous operation, and select-
able power-save provide high efficiency operation over a
wide load range. In power-save mode, the minimum oper-
ating frequency for the SC417 is 25kHz whereas the SC427
has no minimum.
Additional features include internal soft-start, program-
mable cycle-by-cycle over-current limit protection, under
and over-voltage protections and soft shutdown. 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 voltage range, programmable frequency,
and programmable LDO make the device extremely flexible
and easy to use in a broad range of applications. Support is
provided for single cell or multi-cell battery systems in addi-
tion to traditional DC power supply applications.
