Application Scenarios & Design Considerations

125mA, Frequency-Selectable, Switched-Capacitor Voltage Converters

Alternative Part Number

  • LM2662M/NOPB --: Switched-capacitor voltage converter in an SOIC-8 package with comparable input range and output current, widely available and pin-compatible in function.
  • ICL7660ACPA --: Classic charge-pump voltage inverter/regulator offering similar conversion function, though package and current rating should be verified against the design.
  • LT1054CS8#PBF --: Switched-capacitor voltage converter with higher output current capability and similar operating principle, suitable as a functional substitute after checking pinout.
  • TC7660EOA --: Switched-capacitor voltage converter in SO-8 with equivalent inversion/doubling operation and good availability as a functional substitute.
