6 / 14 page  TC682 DS21453D-page 6 2002-2012 Microchip Technology Inc. 4.3 Paralleling Devices Paralleling multiple TC682s reduces the output resistance of the converter. The effective output resistance is the output resistance of a single device divided by the number of devices. As illustrated in Figure , each requires separate pump capacitors C1 and C2, but all can share a single reservoir capacitor. 4.4 -5V Regulated Supply From A Single 3V Battery Figure 4-3 shows a -5V power supply using one 3V battery. The TC682 provides -6V at VOUT, which is regulated to -5V by the negative LDO. The input to the TC682 can vary from 3V to 5.5V without affecting regulation appreciably. A TC54 device is connected to the battery to detect undervoltage. This unit is set to detect at 2.7V. With higher input voltage, more current can be drawn from the outputs of the TC682. With 5V at VIN, 10 mA can be drawn from the regulated output. Assuming 150 source resistance for the converter, with IL –= 10 mA, the charge pump will droop 1.5V.
