PRODUCTION DATA
The switching frequency of the device can be set by a single RT resistor connected between the RT and the AGND pins. The resistor value to set the RT switching frequency (fRT) is calculated as shown in Equation 5.
The RT pin is regulated to 0.5 V by the internal RT regulator when the device is enabled.
