SY26004
SY26004 is 4A 2.4MHz Synchronous Step-Down Regulator manufactured by Silergy.
High-Efficiency, 6V, 4A 2.4MHz Synchronous Step-Down Regulator
General Description
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 resistordivider ponents must be selected for the targeted application specifications.
The SY26004 is available in a space-saving, low-profile DFN2×2-7 package.
