TPS54331DR Description
The TPS54331DR is a nonsynchronous buck converter with a low RDS(on) high-side MOSFET that operates at 28 V and 3 A. A pulse skipping Eco-mode feature is automatically enabled to optimize efficiency under light loads. Additionally, the device's 1-A shutdown supply-current enables it to be employed in battery-powered applications. Current mode control with inbuilt slope compensation decreases component count and simplifies external compensation calculations while allowing the use of ceramic output capacitors. The hysteresis of the input undervoltage lockout is programmed using a resistor divider. During startup and transient conditions, an overvoltage transient protection circuit prevents voltage overshoots. In the event of an overload condition, a cycle-by-cycle current-limit system, frequency foldback, and thermal shutdown protect the device and the load.
TPS54331DR Features
? Switching Frequency: 570 kHz
? Shutdown Quiescent Current: Typical 1-A
? Inrush currents are limited by a slow-start feature that can be adjusted.
? UVLO Threshold that can be programmed
? Protection Against Overvoltage Transients
TPS54331DR Applications
? Set-Top Boxes, CPE Equipment, LCD Displays, Peripherals, and Battery Chargers are examples of consumer applications.
? Power Supplies for Industrial and Automotive Audio
? Distributed Power Systems (5-V, 12-V, and 24-V)
