SLVSDF3F MARCH 2017 – JANUARY 2019 TPSM846C23
The TPSM846C23 is set to a default switching frequency of 500 kHz. To operate the TPSM846C23 at the default switching frequency, connect the RT_SEL pin (pin 14) to AGND, and leave the RT pin (pin 13) open. To change the switching frequency, leave the RT_SEL pin open and connect a resistor from the RT pin (RRT) to AGND. Use Equation 3 to calculate the RRT resistor value.
The TPSM846C23 devices are designed to operate from 300 kHz to 1 MHz.
