SY26004 - 4A 2.4MHz Synchronous Step-Down Regulator

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.

Features

  • Low RDS(ON) for Internal Switches: 25mΩ Top, 17mΩ Bottom.
  • 2.5~6V Input Voltage Range.
  • Up to 4A Output Current.
  • Constant On-time and Ripple-based Control.
  • Low 23µA Quiescent Current.
  • High 2.4MHz Switching Frequency Minimizes Required External Components.
  • Internal Soft-Start Limits Inrush Current.
  • 100% Dropout Operation.
  • Power-Good Indicator.
  • Hiccup Mode for Short-Circuit Protection.
  • Output Auto-Discharge Function.
  • RoHS-Compliant and Hal.

SY26004 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 components must be selected for the targeted application specifications. The SY26004 is available in a space-saving, low-profile DFN2×2-7 package. Features  Low RDS(ON) for Internal Switches: 25mΩ Top, 17mΩ Bottom  2.
