3 A Current Mode Constant On-Time
Synchronous Buck Regulator
DESCRIPTION
The SiP12116 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.
SiP12116’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 2.2 ms and
integrated compensation.
The device also includes cycle-by-cycle current limit, over
temperature protection (OTP) and input under-voltage
lockout (UVLO).
The SiP12116 is available in lead (Pb)-free 3 mm x 3 mm
DFN 10 lead package with thermal pad.
