Overview

Description

The RTKA211805DE0000BU evaluation board provides a simple platform for evaluating the RAA211805 ultra-low quiescent current (IQ) switching regulator in the TSOT23-5 package. The board operates from a supply voltage of 7V to 80VDC, delivering a continuous load up to 300mA at 5V output voltage.

Features

  • 7V to 80V input supply range
  • Up to 300mA output current
  • IQ = 5.5μA at 80V, at no load conditions, switching
  • IQ = 4.5μA at 80V at no load and no switching conditions
  • Fixed 5V VOUT
  • Minimum on-time of 75ns
  • Variable frequency operation, frequency programmed by external inductor (10μH to 33μH)
  • Pre-bias, monotonic, and smooth start-up
  • Protections
    • Overcurrent (OC) limit
    • Input undervoltage lockout (UVLO)
    • Over-temperature protection (OTP)
    • Output overvoltage protection (OVP)
  • Accurate EN threshold
