SY21173 Datasheet | Silergy

High-Efficiency, 3A, 60V Input Asynchronous Buck Converter General Description The SY21173 high-efficiency asynchronous Buck converter can deliver 3A output current over a wide input voltage range from 4.5V to 60V. The SY21173 employs a constant off-time and peakcurrent mode control strategy to achieve fast transient responses. It integrates a main switch with low RDS(ON) to minimize conduction loss. The adjustable switching frequency permits low output-voltage ripple and reduces external inductor and capacitor sizes. The SY21173 also provides cycle-by-cycle current limiting, over temperature protection, and output short circuit protection. The SY21173 is available in a pact...
