SIP12117 Synchronous Buck Regulator Reference Board

The SiP12117 is a high frequency current-mode constant on-time (CM-COT) synchronous buck regulator with integrated high-side and low-side power MOSFETs. Its power stage is capable of supplying up to 3 A continuous current at 600 kHz switching frequency. This regulator produces an adjustable output voltage down to 0.6 V from 4.5 V to 15 V input rail to accommodate a variety of applications, including consumer electronics, computing, telecom, and industrial.SiP12117’s CM-COT architecture delivers ultrafast transient response and low ripple over the full load range with minimum output capacitance and no ESR requirements.The device features a built in soft start of 2.9 ms and integrated compensation.The device also includes cycle-by-cycle current limit, over temperature protection (OTP) and input under-voltage lockout (UVLO).The SiP12117 is available in lead (Pb)-free 3 mm x 3 mm DFN 10 lead package with thermal pad.
