Figure 7-7 shows MAX680 and MAX681 converters used to provide ±10-V outputs from a +5-V input. The input voltage range is +2.0 V to +6.0 V. Voltage-conversion efficiency is 95%, with 85% power-conversion efficiency. The supply current is 500 μA. The output source impedances are typically 150 Ω, providing useful output currents up to 10 mA. No extemal capacitors are required for the MAX681. Figure 7-8 shows a test circuit. Figures 7-9 and 7-10 show typical test results. MAxIM NEw RELEASES DATA BOOK, 1992, P. 4-141.
