Figure 29. Negative Charge Pump Block TPS65167
The output voltage is VGL = (–Vin) + Vdrop. Vdrop is the voltage drop across the external diodes and internal
charge pump MOSFETs.
Setting the output voltage:
Since the reference output driver current should typically not exceed 30
A, the lower feedback resistor value R8
should be in a range of 40 k
to 120 k. The negative charge pump requires two external Schottky diodes. The
peak current rating of the Schottky diode has to be twice the load current of the output. For the external
component selection refer to Table 12.
For a 20-mA output current, the dual Schottky diode BAV99 or BAT54 is recommended.

The TPS65167 has a LDO controller using an external pass transistor. The input of the LDO controller can be
the 12-V power supply input or the output of the 3.3-V logic rail, as generated by the step-down converter. The
LDO controller is connected to the 3.3-V rail in order to minimize power losses across the external pass
transistor.
