  High Voltage Inverting Charge Pump Produces Low Noise
  Positive and Negative Supplies – Design Note 507
  Marty Merchant Inverting Charge Pump
  The LTC3260 can supply up to 100mA from the inverted
  input voltage at its charge pump output, VOUT. VOUT
  also serves as the input supply to a negative LDO
  regulator, LDO –. The charge pump frequency can be
  adjusted between 50kHz to 500kHz by a single external
  resistor. The MODE pin is used to select between a high
  efficiency Burst Mode operation or constant frequency
  mode to satisfy low noise requirements.

  A single resistor at the RT pin sets the constant operating
  frequency of the charge pump. If the RT pin is grounded, …
