The SKY87222 is a dual, 1.2 MHz, Constant On-time synchronous step-down DC-DC converter. The SKY87222 provides a fixed output voltage of 1.8 V and an adjustable output voltage from 0.6 V to 3.3 V from input voltage ranging from 2.7 V to 5.0 V. The SKY87222 provides excellent line and load regulation along with high light load efficiency.

The Constant On-time control allows for easy loop stabilization with minimal external components while providing fast transient response.

Power sequencing is available via EN pins along with a Power Good pin.

The SKY87222 has cycle-by-cycle current limit and thermal shutdown to protect against fault conditions. The SKY87222 is available in a Pb-free, low-profile, 17-pin 2.0 mm x 2.5 mm Quad Flat No-Lead (QFN) package, and rated over the -40 ºC to 85 ºC temperature range.
