High Voltage Inverting Charge Pump Produces Low Noise
Positive and Negative Supplies вЂ“ 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 вЂ“. 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.
