What are the key features of TPS56302PWPG4?
- Dual-channel voltage-mode buck controller in a compact 28-pin HTSSOP-EP package, enabling two independent step-down rails in minimal PCB area
- Operates from 4.5 V to 5.5 V input with adjustable output voltage and programmable soft-start for controlled power sequencing
- Supports synchronous rectification and cycle-by-cycle current limiting for high efficiency and robust overcurrent protection
What is TPS56302PWPG4 used for?
TPS56302PWPG4 is well suited for multi-rail point-of-load power systems in telecom equipment, networking infrastructure, and industrial control boards where two separate regulated DC outputs are required from a single 5 V bus. Its voltage-mode control and programmable soft-start make it an effective choice for powering FPGAs, DSPs, and other sensitive digital loads that demand precise startup sequencing and low output ripple.

Frequently Asked Questions
What input voltage range does the TPS56302PWPG4 support for dual buck operation?
The TPS56302PWPG4 operates from a 4.5 V to 5.5 V input supply, making it compatible with standard 5 V system rails. Both channels share the same input rail, and each output voltage is independently adjustable through external resistor dividers, allowing flexible multi-rail designs without additional regulators.
Which industrial or telecom designs benefit most from TPS56302PWPG4 dual-channel architecture?
Designs that require two independently regulated outputs from a single 5 V bus — such as FPGA core plus I/O rails, or DSP plus memory supplies — benefit most. The 28-pin HTSSOP-EP package keeps thermal resistance low, supporting continuous dual-channel operation in space-constrained 19-inch rack modules and embedded computing boards running at up to 5.5 V input.
How does the TPS56302PWPG4 compare to a single-channel TPS56x solution when BOM cost is critical?
Using TPS56302PWPG4 consolidates two independent buck controllers into one 28-pin HTSSOP-EP IC, reducing total component count, PCB area, and BOM line items compared to two separate single-channel devices. For systems needing exactly 2 step-down rails from a 5 V input, this integration typically lowers assembly cost and simplifies layout routing of power planes.
