iC-DC    Programmable Dual 2.5/3.3/5 V Buck/Boost SMPS

  • Dual voltage supply by buck/boost converters with adjustable, back-end linear regulators
  • Power management for laser, encoder, and automotive applications
  • Wide input voltage range of 4 to 36 V
  • Reverse polarity protection up to -36 V with autarky function
  • Universal buck/boost converter with high efficiency
  • Two back-end, adjustable linear regulators (1.5 to 5.5 V) with a total of up to 300 mA of output current and a separate output voltage monitor
  • Low residual ripple with small capacitors in the μF range
  • Separate enable inputs for the linear regulators
  • Two switched outputs referenced to the linear regulators
  • Integrated switching transistors and flyback diodes
  • Converter cut-off current can be set by an external resistor
  • Integrated 3 MHz oscillator with no external components
  • Active noise spectrum reduction
  • Error messaging with overtemperature, overvoltage, and undervoltage at the current-limited open-collector output
  • Wide temperature range of -40 to 125°C
  • Protective circuitry against ESD
  • QFN package requires little space and few external components
