JAJSGC8B October 2018 – January 2020 TPS25982
PRODUCTION DATA.
This design example considers a 12-V system operating voltage with a tolerance of ±10 %. The rated load current is 12 A. If the current exceeds 15 A, then the device must allow overload current for 2-ms interval before breaking the circuit and then restart. Accordingly, the TPS259824O variant is chosen. (Refer to Device Comparison Table for device options.) Ambient temperatures may range from 20 °C to 70 °C. The load has a minimum input capacitance of 1.4 mF and start-up resistive load of 10 Ω. The downstream load is turned on only after the PG signal is asserted.
