SNVSCI1A October 2023 – December 2023 TPSM365R1 , TPSM365R15
PRODUCTION DATA
The select variants in the TPSM365R1x family with the RT pin allow the power designers to set any desired operating frequency between 200 kHz and 2.2 MHz in their applications. See Figure 7-6 to determine the resistor value needed for the desired switching frequency. See Table 7-2 for selection on programming the RT pin.
RT INPUT | SWITCHING FREQUENCY |
---|---|
VCC | 1 MHz |
GND | 2.2 MHz |
RT to GND | Adjustable according to Figure 7-6 |
Float (not recommended) | No switching |
Equation 1 can be used to calculate the value of RT for a desired frequency.
