JAJSIO5B July 2019 – February 2020 LMR36506-Q1
ADVANCE INFORMATION for pre-production products; subject to change without notice.
A resistor tied to the LMR36506-Q1 RT pin and GND is used to set the desired operating frequency between 200 kHz and 2.2 MHz. See Figure 3 to determine the resistor value needed for the desired switching frequency. The RT pin and the MODE/SYNC pin variants share the same pin location. The power supply designer can either use the RT pin variant and adjust the switching frequency of operation as warranted by the application or use the MODE/SYNC variant and synchronize to an external clock signal.
