TPS5430DDAR Description
The TPS5430DDAR is a high-output-current PWM converter with a high-side N-channel MOSFET with low resistance. A high-performance voltage error amplifier provides tight voltage regulation accuracy under transient conditions; an undervoltagelockout circuit prevents start-up until the input voltage reaches 5.5 V; an internally set slow-start circuit to limit inrush currents; and a voltage feedforward circuit to improve transient response are all included on the substrate with the listed features. Shutdown supply current is normally decreased to 18A via the ENA pin.
TPS5430DDAR Features
? Internal Compensation Reduces the Number of External Parts
? Switching Frequency of 500 kHz for Small Filter Size
? Input Voltage Feed Forward improves line regulation and transient response.
? Overcurrent limiting, overvoltage protection, and thermal shutdown protect the system.
TPS5430DDAR Applications
? Consumer Electronics: Set-top Boxes, DVD Players, and LCD Monitors
? Audio Power Supplies for Industry and Automobiles
? Chargers for batteries and high-power LED lighting
? Distributed Power Systems (12-V/24-V)
