Voltage ID DAC input
Voltage ID DAC input. Pull to V CC (5 V) to enable AMD 6 ? bit DAC code.
A resistance from this pin to ground programs the oscillator frequency and provides a 2 V reference
for programming the ILIM voltage.
Over current shutdown threshold setting. ILIM = VDRP ? 1.3 V. Resistor divide ROSC to set threshold
0 to 1 Volt analog signal proportional to the output load current. VSN referenced Clamped to 1.1 Vmax
