manufacturer: description:note 5: minimum bias voltage is the voltage on the bias pin when ibias is sourced into the pin. note 6: this is the minimum voltage across the boost capacitor needed to guarantee full saturation of the internal power switch. note 7: boost current is the current flowing into the boost pin with the pin held 3.3v above input voltage. it flows only during switch on time. note 8: gain is measured with a vc swing from 1.15v to 750mv. note 9: switch on resistance is calculated by dividing vin to sw voltage by the forced current (1.5a). see typical performance characteristics for the graph of switch voltage at other currents. note 10: the css threshold is defined as the value of current sourced into the css pin which results in an increase in sink current from the vc pin. see the soft-start section in applications information. note 11: the pgfb threshold is defined as the percentage of vref voltage which causes the current source output of the ct pin to change from sinking (below threshold) to sourcing current (above threshold). when sourcing current, the voltage on the ct pin rises until it is clamped internally. when the clamp is activated, the output of the pg pin will be set to a high impedance state. when the ct clamp is inactive the pg pin will be set active low with a current sink capability of 200µa. |
