SY26406SXC - Synchronous Step Down Regulator

Description

The SY26406 develops a high efficiency synchronous step-down DC/DC converter capable of delivering 0.6A current.

The SY26406 operates over a wide input voltage range from 7V to 100V and integrates a main switch and a synchronous switch with very low RDS(ON) to minimize the conduction loss.

Features

  • Wide Input Voltage Range: 7-100V.
  • Internal 500mΩ Main Switch and 285mΩ Synchronous Switch.
  • 0.6A Output Current Capability.
  • COT Ripple-Based Control to Achieve Fast Transient Responses.
  • Programmable Switching Frequency Range: 200kHz~1MHz.
  • 2ms Internal Soft-start Limits the Inrush Current.
  • Accurate Feedback Set Point: 1.225V±2%.
  • Cycle-by-cycle Peak/Valley Current Limit.
  • Cycle-by-cycle Reverse Current Limit.
  • Auto Recovery for Over Temperature (OTP).
