DescriptionAs a member of one of TI’s families of dc/dc regulators, the TPS54310PWPG4 low-input-voltagehigh- 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 erroramplifier that provides high performance under transient conditions; an undervoltage-lockoutcircuit to prevent start-up until the input voltage reaches 3 V; an internally and externally setslow-start circuit to limit in-rush currents; and a power good output useful for processor/logicreset, fault signaling, and supply sequencing.
The TPS54310PWPG4 device is available in a thermally enhanced 20-pin HTSSOP (PWP)PowerPAD? package, which eliminates bulky heatsinks. TI providesevaluation modules to aid in quickly achieving high- performance power supply designs to meetaggressive equipment development cycles.
Feature
- 60-m? MOSFET switches for high efficiency at 3-A continuous output source or sinkcurrent
- Adjustable output voltage down to 0.9 V With 1% accuracy
- Externally compensated for design flexibility
- Fast transient response
- Wide PWM frequency: fixed 350 kHz, 550? kHz, or adjustable 280 kHz to 700kHz
- Load protected by peak current limit and thermal shutdown
- Integrated solution reduces board area and total cost
