Datasheet Summary
High Efficiency Fast Response, 98% Duty, 6A, 30V Input Synchronous Buck Converter
General Description
The SY21219 high efficiency 500kHz synchronous buck converter operates over a wide input voltage range of 4.5V to 30V, and can deliver an output current up to 6A. It integrates a top MOSFET and a bottom MOSFET with very low RDS(ON) to minimize conduction loss. The 500kHz pseudo-constant switching frequency enables using small external inductor and capacitor values.
Silergy’s constant on-time and ripple-based control strategy supports high input/output voltage ratios (low duty cycles), and fast transient response while maintaining a near constant operating frequency over line, load...
