Hello Hardy,
TLV62084 is 2A rating converter. Why the current limit has < 2?
TLV62084 has cycle by cycle over current protection. This means during the over current event, inductor peak-current limit measures the current during the high-side and low-side power MOSFET on-phase. Once the high-side switch current-limit is tripped, the high-side MOSFET is turned off and the low-side MOSFET is turned on to reduce the inductor current. When the inductor current drops down to the low-side switch current-limit, the low-side MOSFET is turned off and the high-side switch is turned on again. This operation repeats until the inductor current does not reach the high-side switch current-limit. Because of an internal propagation delay, the real current-limit value exceeds the static-current limit in the Electrical Characteristics table.
1.8 A is the Min limit across – 40 to 150 °C temperature variation, we make sure that the average DC current will be 2A.
Thank you & regards,
Moheddin.
