JAJSJ29D May 2020 – October 2021 TPS61378-Q1
PRODUCTION DATA
The TPS61378-Q1 uses a fixed-frequency control scheme. The switching frequency can be programmed between 200 kHz and 2.2 MHz using a resistor from the FREQ pin to GND. The resistor must be connected when the oscillator is synchronized by an external clock. The resistance is defined by Equation 1.
where
For example, the switching frequency is 2.2 MHz if the resistance between the FREQ pin and GND is 18 kΩ. This pin cannot be left floating or tied to VCC.
