SLVSES4D September 2019 – June 2024 TPS54J060
PRODUCTION DATA
The TPS54J060 provides forced CCM operation for tight output ripple application and auto-skipping Eco-Mode for high light-load efficiency. The device allows users to select the switching frequency and operation mode by using the MODE pin. Table 6-1 lists the resistor values for the switching frequency and operation mode selection. TI recommends 1% tolerance resistors with a typical temperature coefficient of ±100 ppm/°C.
The MODE status will be set and latched during the MODE pin calibration time. Changing the MODE pin resistance after the calibration time will not change the status of the device.
To make sure internal circuit detects the desired setting correctly, do not place any capacitor on the MODE pin.
