SY21288A

Overview

The SY21288A is a high efficiency synchronous buck converter operating over a wide input voltage range of 4V to 24V and capable of delivering up to 8A current. It integrates low RDS(ON) top and bottom MOSFETs to minimize the conduction loss.

  • Low RDS(ON) for Internal MOSFETs: 20mΩ Top, 10mΩ Bottom
  • Wide Input Voltage Range: 4V ~ 24V
  • Adjustable Output Voltage: 0.6V ~ 12.5V
  • Large Duty Cycle On-Time Stretch
  • 8A Continuous Output Current Capability
  • 600kHz Pseudo-Constant Frequency
  • ±1% Internal Reference Voltage
  • Internal 1ms Soft-Start Limits the Inrush Current
  • Constant On-Time and Ripple-Based Control to Achieve Fast Transient Responses
  • Integrated 1.5Ω Bypass Switch
