Applications
The TPS54283PWPG4 is designed for multi-rail power supplies in industrial automation, telecommunications infrastructure, and embedded computing boards that require dual regulated voltages from a single wide-range input bus. Its 4.5V to 28V input range makes it compatible with 12V, 24V, and 19V power architectures found in rack-mount servers, networking switches, and motor control systems. The current-mode PWM topology provides fast transient response and inherent cycle-by-cycle current limiting for robust protection in demanding environments.

Frequently Asked Questions
What are the input and output voltage ranges of the TPS54283PWPG4?
The TPS54283PWPG4 accepts input voltages from 4.5V to 28V with a nominal 12V input, and provides dual adjustable output voltages from 0.8V to 25.2V at up to 2A per channel. It can also operate in fixed-voltage modes depending on external resistor configuration.
How many output channels does the TPS54283PWPG4 support?
The TPS54283PWPG4 is a dual switching controller, meaning it manages two independent step-down output channels simultaneously. This makes it ideal for powering two separate voltage rails (for example, a core and I/O supply) from a single IC, reducing component count and board space.
What control topology does the TPS54283PWPG4 use?
The TPS54283PWPG4 uses current-mode pulse width modulation (PWM) control, which provides inherent cycle-by-cycle current limiting, improved transient response over voltage-mode control, and simplified compensation design, making it well suited for industrial and high-reliability power supply applications.
What package does the TPS54283PWPG4 come in, and is it RoHS compliant?
The TPS54283PWPG4 is housed in a 14-pin HTSSOP (Heatsink Thin Shrink Small Outline Package) with an exposed thermal pad for improved heat dissipation. It carries JESD-609 code e4, confirming full RoHS compliance and lead-free construction compatible with modern SMT assembly processes.
What is the maximum output current of the TPS54283PWPG4?
The TPS54283PWPG4 supports up to 2A of output current per channel. With two channels operating simultaneously at 2A, it can supply a total of 4A across both output rails from a single controller IC, making it efficient for multi-load embedded power architectures.
