High efficiency DC-DC converter designed in GF 22FDX with full PWM operation mode. Can be configured with output current from 100 mA to 2A

Key Benefits

  • Works with a smaller inductance size compared to previous product generation
  • High efficiency buck regulator (up to 95% peak), over wide load current range
  • Pulse With Modulation (PWM) mode enabling to master the frequency response when supplying noise-sensitive analog loads
  • Automatic mode change of the Power Stage Unit, maintaining high-efficiency at low load current
