SY21199C
SY21199C is 600mA Step-Up Regulator manufactured by Silergy.
High Efficiency 1MHz, 600m A Step-Up Regulator
General Description
The SY21199C high efficiency step-up regulator is targeted at general applications and can deliver 600m A 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 pensation reduce external inductor and capacitor sizes.
The SY21199C is available in a pact SOT23-6 package.
