FUNCTION
Negative Terminal of the Doubler Charge-Pump Capacitor. See Table 2 for capacitor selection.
Ground
Negative Terminal of the Inverter Charge-Pump Capacitor
Inverter Charge-Pump Output. See Table 2 for capacitor selection.
Negative Regulator Output. See Table 2 for capacitor selection.
Set Negative Output Voltage Input. Connect SETN to GND for factory-preset -5V. Connect a resistor
divider between NOUT, SETN, and GND for custom output voltage setting.
Negative-Supply Shutdown Input. Pull NSHDN low to turn off the inverting charge pump, the negative reg-
ulator, and the bias-ready indicator. If PSHDN is also low, the part completely shuts down.
Positive-Supply Shutdown Input. Pull PSHDN low to turn off the positive regulator. If NSHDN is also low,
the part completely shuts down.
Clock Synchronizing Input. Connect an external 20kHz ≤ f CLK ≤ 240kHz to SYNC to synchronize the
MAX768 to that frequency. Connect SYNC to GND to select the internal 25kHz clock, or to IN for the inter-
nal 100kHz clock.
Output-Ready Indicator. This open-drain output pulls to GND when the negative output voltage (NOUT) is
within 10% of the regulation voltage.
Set Positive Output Voltage Input. Connect SETP to GND for factory-preset +5V output. Connect a resistor
divider between POUT, SETP, and GND for custom output voltage setting.
Positive Regulator Output. See Table 2 for capacitor selection.
Doubler Charge-Pump Output. See Table 2 for capacitor selection.
Positive Terminal of the Doubler Charge-Pump Capacitor. See Table 2 for capacitor selection.
Supply (3V to 5.5V). Bypass IN with 4.7μF to GND.
Positive Terminal of the Inverter Charge-Pump Capacitor. See Table 2 for capacitor selection.
