7.4.2 MODE Pin Configuration

The MODE pin is used to select hiccup mode current limit. The MODE selection is based on the voltages at the

MODE pin. The MODE voltage is decided by the programming resistor, RMODE, between MODE and AGND, and

the source current out of the MODE pin (IMODE). MODE is latched during start-up.
