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-mΩ 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.
• Fixed 500-kHz Switching Frequency for Small Using the ENA pin, shutdown supply current is
Filter Size reduced to 18 μA typically. Other features include an
active-high enable, overcurrent limiting, overvoltage • 18-μA Shutdown Supply Current protection and thermal shutdown. To reduce design
• Improved Line Regulation and Transient complexity and external component count, the
Response by Input Voltage Feed Forward TPS5450 feedback loop is internally compensated.
