iC-WDB    Switched-Mode 3.3 V (200 mA) and 5 V Regulators for 8 V to 36 V

Applications
  • 5 V resp. 3.3 V supply e.g. from 24 V industrial network
Features
  • Input voltage 8 to 36 Vdc
  • Highly efficient down converter
  • Switching transistor and free-wheeling diode integrated
  • Adjustment of the regulator cut-off current with external resistor
  • Integrated 100 kHz oscillator without external components
  • Switching frequency above the audible range
  • Two downstream linear regulators with 200 mA/25mA output current
  • Three different output voltage combinations of 3.3V version available (see Block Diagram)
  • Small residual ripple with low capacitances in the μF range
  • Fault message at overtemperature and undervoltage at current-limited open-collector output
  • Shutdown of switching regulator at overtemperature
  • Internal reference voltages
  • ESD protection
  • Low space requirement with SO8 resp. tiny DFN10 package
  • Option: enhanced temperature range of -40 to 85 C
