    The SY21199C high efficiency step-up regulator is targeted at general applications and can deliver 600mA current over a wide input voltage range from 3V to 25V. It integrates an N-channel MOSFET with low 150mΩ RDS(ON) to minimize conduction loss.

    The 1MHz switching frequency and internal compensation reduce external inductor and capacitor sizes.

    The SY21199C is available in a compact SOT23-6 package.
