General Description

SY8204 develops a high efficiency synchronous stepdown DC-DC converter capable of delivering 4A output current.

SY8204 operates over a wide input voltage range from 4.5V to 30V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

SY8204 adopts the proprietary instant PWM architecture to achieve fast transient responses for high step down applications and high efficiency at light loads.

Key Features

  • Low RDS(ON) for internal switches (top/bottom): 80/50 mΩ.
  • 4.5-30V input voltage range.
  • Instant PWM architecture to achieve fast transient responses.
  • External softstart limits the inrush curre t.
  • Pseudo-constant frequency: 500kHz at heavy loads.
  • 4A continuous, 5A peak load current capability.
  • 1.5% 0.6V reference.
  • Output over current limit.
  • Output short circuit p otection with current fold back.
  • Thermal shut.
