The SY26004 high efficiency 2.4MHz synchronous Buck converter operates over a wide input voltage range from 2.5V to 6V and is capable of delivering up to 4A output current. It integrates a top FET and a bottom FET with very low RDS(ON) to minimize conduction loss.
The SY26004 adopts a constant on-time and ripple-based control strategy to achieve fast transient responses. The input and output capacitors, the inductor, and the resistor-divider components must be selected for the targeted application specifications.
The SY26004 is available in a space-saving, low-profile DFN2×2-7 package.
