A MAX634 inverting regulator is combined with a MAX630 to provide a dual tracking ±15 output from a 12-V battery. The reference for the -15 V output is derived from the positive output via R3 and R4.

Both regulators are set to maximize output power at low battery voltages by reducing the oscillator frequency, via LBR, when "BATT falls to 8.5 V.
