-14V/150mA Inverting BuckBoost Reference Design


Design files


Modified step-down converter PMP2763 to an inverting flyback.  Could be easily changed to -15V output to provide negative rail out with a 15V input.

  • Low output ripple
  • Very good line and load regulation
  • No ringing, no overshoot at the switchnode waveforms
  • Loop is optimized for best dynamic perfomance (designed for pulsed load)
Output voltage options PMP10210.1
Vin (Min) (V) 9
Vin (Max) (V) 18
Vout (Nom) (V) -14
Iout (Max) (A) .15
Output Power (W) 2.1
