General Description

The SY8805A is a high-efficiency 1 MHz synchronous step-down DC-DC regulator, Current Mode Control IC capable of delivering up to 5A output current.

The SY8805A operates over a wide input voltage range from 3V to 5.5V.

It integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

Key Features

  • Low RDS(ON) for internal switches (top/bottom): 35/15 mohm.
  • 3-5.5V input voltage range.
  • 1 MHz switching frequency minimizes the external components.
  • Internal softstart limits the inrush current.
  • Up to 98% efficiency.
  • 0.6V reference voltage.
  • Shutdown mode draws.
