Product Description


HiSAT-COT 1.0A Synchronous Step-Down DC/DC Converter

The XC9286 series, is a step-down synchronous DC/DC converter with a built-in P-channel driver FET and a N-channel driver FET. The IC provides a high efficiency (Typ 92%) and a stable power supply with output currents of up to 1.0A achievable using only a coil and two ceramic capacitors connected externally. Quiescent current is only 15μA.

Minimum operating voltage is 2.5V and output voltage is fixed within a range of 0.8V to 3.6V in 50mV steps (accuracy: ± 2.0%). Switching frequency is 1.2MHz.

The soft start and current control functions are internally optimized. Soft-start is 0.3ms typically.

During standby, all circuits are shutdown to reduce current consumption to as low as 1.0μA max.

Available in USP-6C and SOT-25 packages.
