Frequently Asked Questions
What is the input voltage range of the TPS54356PWPG4?
The TPS54356PWPG4 operates from an input voltage range of 4.5 V to 20 V with a nominal input of 12 V, making it compatible with standard 5 V and 12 V power rails commonly used in industrial and embedded electronics systems.
What output current can the TPS54356PWPG4 deliver?
The TPS54356PWPG4 provides up to 3 A of continuous output current at 3.3 V, making it suitable for powering microprocessors, FPGAs, and other moderate-power loads in industrial automation, embedded computing, and telecom applications.
What control method does the TPS54356PWPG4 use?
The TPS54356PWPG4 uses voltage-mode pulse-width modulation (PWM) control, which provides predictable loop dynamics, straightforward compensation design, and stable regulation performance over a wide range of input voltages and load conditions.
What package is the TPS54356PWPG4 available in?
The TPS54356PWPG4 is packaged in a 16-pin HTSSOP (thermally-enhanced thin shrink small outline package), which includes an exposed thermal pad for improved heat dissipation, enabling higher output current handling in a compact surface-mount form factor.
Is the TPS54356PWPG4 a synchronous or non-synchronous regulator?
The TPS54356PWPG4 is a synchronous buck regulator with integrated high-side and low-side power MOSFETs. The synchronous topology eliminates the need for an external freewheeling diode and improves overall power conversion efficiency, especially at high output current levels.
