PRODUCTION DATA
In some cases, an input UVLO level different than that provided internal to the device is required. Based on the circuit shown in Figure 9-1, VIN(on) and VIN(off) designate the input voltages thresholds at which the converter turns on and off, respectively. First, choose a value for the lower resistance RENB in the range of 10 kΩ to 100 kΩ. Then use Equation 14 to calculate the upper resistance RENT based on a target input voltage turn-on threshold of 5.9 V.
Selecting upper and lower resistances of 365 kΩ and 100 kΩ gives input voltage turn-on and turn-off thresholds of 5.87 V and 4.23 V, respectively.
