9.1.3 Generation of Dual Polarity Voltages from Two Self-Synchronized DCR01s
Two DCR01s can be configured to produce a dual polarity supply (that is, ±5 V); the circuit must be connected as shown in Figure 9-3.
Observe that both devices are producing a positive regulated output; therefore the ERROR, ENABLE, and VREC are all relative to the –VOUT pin of that particular device and must not be directly connected together, or in the case of the negative output device, connected to the common 0-V output.
A. CIN = 2.2 μF for 5-V input devices and
0.47 μF for 12-V and 24-V input devices. Low-ESR, ceramic capacitors are required.
