TPS5450 5-A, Wide Input Range, Step-Down Converter

1 Features

? Wide Input Voltage Range: 5.5 V to 36 V The TPS5450 is a high-output-current PWM

converter that integrates a low-resistance, high-side

? Up to 5-A Continuous (6-A Peak) Output Current N-channel MOSFET. Included on the substrate with

? High Efficiency Greater Than 90% Enabled by the listed features are a high-performance voltage

110-m? Integrated MOSFET Switch error amplifier that provides tight voltage regulation

accuracy under transient conditions; an undervoltage- ? Wide Output Voltage Range: Adjustable Down to

lockout circuit to prevent start-up until the input 1.22 V With 1.5% Initial Accuracy

voltage reaches 5.5 V; an internally set slow-start

? Internal Compensation Minimizes External Part circuit to limit inrush currents; and a voltage feedCount

forward circuit to improve the transient response.
