General Description

The SYVM78A develops a high efficiency asynchronous step down DC/DC regulator, which is capable of delivering 0.8A output current.

The IC adopts current mode adaptive constant off time control.

The SYVM78A operates over a wide input voltage range from 4.5V to 55V and integrates main switch with very low RDS(ON) to minimize the conduction loss.

Key Features

  • Low RDS(ON) for Internal N-channel Power FET: 700mΩ.
  • 4.5-55V Input Voltage Range.
  • 0.8A Output Current Capability.
  • 1.5MHz Pseudo Constant Switching Frequency.
  • Internal Soft-start Limits the Inrush Current.
  • Hic-cup Mode Output Short Circuit Protection.
  • EN ON/OFF Control with Accurate Threshold.
  • Cycle by Cycle Peak Current Limit.
  • Meet 0.1% Output Voltage Ripple Request in Power Meter.
