SY8501 - Synchronous Step Down Regulator

Description

SY8501 develops high efficiency synchronous stepdown DC-DC converter capable of delivering 1.0A current.

The SY8501 operates over a wide input voltage range from 7V to 100V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

Features

  • low RDS(ON) for internal switches (top/bottom): 500mΩ/240mΩ.
  • 7-100V input voltage range.
  • 1A output current capability.
  • Adjustable switching frequency.
  • Instant PWM architecture to achieve fast transient responses.
  • 2ms internal softstart limits the inrush current.
  • Precious +/-2% 1.2V reference.
  • RoHS Compliant and Halogen Free.
  • Compact SO8E package.
