... Generally, ΔI should be set to approximately 20% of the maximum output current. Since the maximum L output current of the TCV7102AF is 3.8A, ΔI rating greater than the peak output current of 4.2A. If the inductor current rating is exceeded, the inductor becomes saturated, leading to an unstable DC-DC converter operation and ...

... C SS2 SS The soft-start feature is activated when the TCV7102AF exits the undervoltage lockout (UVLO) state after power-up and when the voltage at the EN pin has changed from logic low to logic high. Overcurrent Protection(OCP) TCV7102AF has an overcurrent protection with latch function. When a peak current ...

... The TCV7102AF provides thermal shutdown. When the junction temperature continues to rise and reaches T (150°C typ.), the TCV7102AF goes into thermal shutdown and shuts off the power supply. TSD has a SD hysteresis of about 15°C (typ.). The device is enabled again when the junction temperature has dropped by approximately 15° ...
