Description Cuk Switching Regulator IC Negative Adjustable -1.255V 1 Output 1A (Switch) SOT-23-5 Thin
Key Features
  • High-Speed Switching: Fixed switching frequency of 1.2MHz enables use of small, low-cost capacitors and inductors with height ≤2mm.
  • Negative Output Generation: Can produce -5V output at 350mA or -12V output at 150mA from 5V input.
  • Dual-Inductor Topology: Filters both input-side and output-side currents, achieving ≈1mV(P-P) ripple with ceramic capacitors.
  • Fixed-Frequency Switching: Ensures clean output without low-frequency noise typical in charge-pump solutions.
  • Wide Input Range: 2.6V to 16V input voltage range with 36V switch allowing 34V differential between VIN and VOUT.
  • Low-Impedance Output: Maintains within 1% of nominal value during large load steps.
  • Current-Mode Control: Constant-frequency scheme provides excellent voltage/load regulation with 1.2A current limit.
  • Compact Design: 5-pin ThinSOT package for space-constrained applications.
