Figure 45. External Switch for Increased Negative Output Current
The output current capability of the MAX828 and MAX829 can be extended beyond 600 mA with the addition of two
external switch transistors and two Schottky diodes. The output voltage is approximately equal to V
in
minus the sum of the
base emitter drops of both transistors and the forward voltage of both diodes. The performance characteristics for the converter
are shown below. Note that the output resistance is reduced to 0.9 and 1.0 ohms for the 828 and 829 respectively.
