JAJSJ29D May 2020 – October 2021 TPS61378-Q1
PRODUCTION DATA
The TPS61378-Q1 adopts a cycle-by-cycle peak current limit internally. The low-side switch is turned off immediately as soon as the switch peak current triggers the limit threshold. The peak switch current limit can be set by a resistor from the ILIM pin to ground. The relationship between the current limit and the resistor is shown in Equation 2.
where
For instance, the current limit is set to 4.8 A if the RLIM is 20 kΩ. This pin cannot be left floating or connected to VCC.
