SLVSFF2A February 2022 – April 2022 LM5152-Q1 , LM51521-Q1
PRODUCTION DATA
The switching frequency of the device is set by a single RT resistor connected between RT and AGND if no external synchronization clock is applied to the SYNC pin. The resistor value to set the RT switching frequency (RT) is calculated as follows.
The RT pin is regulated to 0.5 V by an internal RT regulator when the device is in active mode or during the device configuration. The switching frequency can be dynamically programmed during operation as shown in Figure 9-8.
