Product Summary

The TPS5420QDRQ1 is a high-output-current PWM converter that integrates a low-resistance high-side N-channel MOSFET. Included on the substrate with the listed features is a high-performance voltage error amplifier that provides tight voltage regulation accuracy under transient conditions, an under voltage-lockout circuit to prevent start-up until the input voltage reaches 5.5 V, an internally set slow-start circuit to limit inrush currents, and a voltage feed-forward circuit to improve the transient response. The applications of the TPS5420QDRQ1 include Industrial and Car Audio Power Supplies, Battery Chargers, High-Power LED Supplies, 12-V/24-V Distributed Power Systems.
