Increasing Output Voltage by Cascading Devices 9.2.2.3 Combined Doubler and Inverter In Figure 14, the LM2664 is used to provide a positive voltage doubler and a negative voltage converter. Note that the total current drawn from the two outputs should not exceed 50 mA. Figure 14. Combined Voltage Doubler and Inverter 9.2.2.4 Regulating VOUT It is possible to regulate the negative output of the LM2664 by use of a low dropout regulator (such as LP2980). The whole converter is depicted in Figure 15. This converter can give a regulated output from −1.8 V to −5.5 V by choosing the proper resistor ratio: VOUT = Vref (1 + R1/R2) (5) where, Vref = 1.23 V (6) Note that the following conditions must be satisfied simultaneously for worst case design: Vin_min > Vout_min + Vdrop_max (LP2980) (7) + Iout_max × Rout_max (LM2664) (8) Vin_max < Vout_max + Vdrop_min (LP2980) (9) + Iout_min × Rout_min (LM2664) (10) space Copyright © 1999–2014, Texas Instruments Incorporated Submit Documentation Feedback 11 Product Folder Links: LM2664 |
