APPLICATIONS

Note

External divider network needed

• Point of load regulation for low-power processors,

network processors, DSPs, FPGAs, and ASICs

•

• Low voltage, distributed power architectures with 5 V or

12 V, or 24 V rails

DESCRIPTION

The SiC401, SiC402, and SiC403 are high frequency

voltage-mode constant-on-time (CM-COT) synchronous

buck regulators with integrated high-side and low-side

power MOSFETs. The SiC403 is capable of 6 A continuous

current, the SiC402 is capable of 10 A and the SiC401 15 A.

These regulators produce an adjustable output voltage

which in standard setup can output 5 V down to 0.6 V

and with the V_OUTdivider network 75 % of V_INdown to

0.6 V to accommodate a variety of applications, including

computing, consumer electronics, telecom, and industrial.

• Computing, broadband, networking, LAN / WAN, optical,

test, and measurement

• A / V, high density cards, storage, DSL, STB, DVR, DTV,

industrial PC

10 A

15 A

The CM-COT architecture delivers ultra-fast transient

response with minimum output capacitance and tight ripple

regulation at very light load. The parts are stable with any

capacitor type and no ESR network is required for loop

stability. The regulator integrates a full protection feature

set, it also has UVLO for the input rail and an internal

soft-start.

SiC401DB-HC

Notes

•

LC - low current inductor, HC - high current inductor

The only difference between HC and LC board is the O / P

inductor size

The SiC40X family is available in lead (Pb)-free power

enhanced 5 mm x 5 mm MLP55-32L package.
