Frequently Asked Questions
What is the TPS54872PWPG4 and what does it do?
The TPS54872PWPG4 is a voltage-mode PWM synchronous buck switching regulator from Texas Instruments. It accepts a 4 V to 6 V input (nominal 4.5 V) and steps down the voltage to a lower regulated output using pulse width modulation control. It is designed for efficient point-of-load DC-DC conversion in digital and embedded systems.
What control mode does the TPS54872PWPG4 use, and why does it matter?
The TPS54872PWPG4 uses voltage-mode PWM control, where the duty cycle is set by comparing a sawtooth ramp to a voltage error signal. Voltage-mode control offers straightforward single-loop compensation, predictable behavior, and good noise immunity, making it easier to stabilize across a range of output capacitors compared to current-mode alternatives. This simplifies PCB design for power supply engineers.
What package does the TPS54872PWPG4 use?
The TPS54872PWPG4 is housed in a 28-pin SOIC package identified by JEDEC code R-PDSO-G28. The JESD-609 code e4 confirms it is lead-free and RoHS-compliant. The SOIC package is compatible with standard automated SMT assembly using pick-and-place machines and reflow soldering ovens, making it suitable for both prototyping and high-volume production.
What input voltage range does the TPS54872PWPG4 support?
The TPS54872PWPG4 operates with an input voltage range of 4 V minimum to 6 V maximum, with a 4.5 V nominal input. This narrow input range targets 5 V bus-powered applications typical in computing and embedded systems. Designers should ensure the input supply remains within this range to avoid under-voltage or over-voltage conditions affecting regulation performance.
What are typical applications for the TPS54872PWPG4?
Typical applications include point-of-load power regulation for DSPs, FPGAs, microprocessors, and memory modules in embedded computing, networking cards, and industrial control boards. The synchronous buck topology is also used for core voltage generation in communication infrastructure equipment and test instrumentation powered from a 5 V system rail.
