TPS54310PWPRG4

Product Summary

The TPS54310PWPRG4 is one member of the TPS54310 series. As members of the SWIFT family of dc/dc regulators, the TPS54310PWPRG4 low-input-voltage high-output-current synchronous-buck PWM converter integrates all required active components. Included on the substrate with the listed features are a true, high performance,voltage error amplifier, TPS54310PWPRG4 provides high performance under transient conditions; an undervoltage-lockout circuit to prevent start-up until the input voltage reaches 3 V; an internally and externally set slow-start circuit to limit in-rush currents; and a power good output useful for processor/logic reset, fault signaling, and supply sequencing. The applications of the TPS54310PWPRG4 are: (1)Low-Voltage, High-Density Systems With Power Distributed at 5 V or 3.3 V; (2)Point of Load Regulation for High Performance DSPs, FPGAs, ASICs, and Microprocessors; (3)Broadband, Networking and Optical Communications Infrastructure; (4)Portable Computing/Notebook PCs.

Parametrics

TPS54310PWPRG4 absolute maximum ratings: (1)storage temperature range: -65 to 150℃;(2)lead temperature range: 300℃;(3)input supply voltage: -0.3 to 7V;(4)Source current: 6mA.

Features

TPS54310PWPRG4 features:(1)60-m MOSFET switches for high efficiency at 3-A continuous output source or sink current; (2)0.9-V to 3.3-V adjustable output voltage with 1% accuracy; (3)externally compensated for design flexibility; (4)fast transient response; (5)wide PWM frequency: fixed 350 kHz, 550 kHz, or adjustable 280 kHz to 700 kHz; (6)load protected by peak current limit and thermal shutdown; (7)integrated solution reduces board area and total cost.The TPS54310 device is available in a thermally enhanced 20-pin TSSOP (PWP) PowerPAD package, which eliminates bulky heatsinks. TI provides evaluation modules and the SWIFT designer software tool to aid in quickly achieving high-performance power supply designs to meet aggressive equipment development cycles.
