SLVS412E –DECEMBER 2001–REVISED DECEMBER 2014
3-V to 6-V Input, 3-A Output Synchronous-Buck PWM Switcher With Integrated FETs
(SWIFT™) Features 3 Description
members of the SWIFT™ family of dc/dc 60-mΩ MOSFET Switches for High Efficiencyat regulators, the TPS54310 low-input-voltage high-3-A Continuous Output Sourceor Sink Current output-current synchronous-buck PWM converter• Adjustable Output Voltage Downto 0.9V With 1% integrates all required active components. IncludedAccuracy on the substrate with the listed features area true,
high performance, voltage error amplifier that• Externally Compensatedfor Design Flexibility
provides high performance under transient conditions;• Fast Transient Response an undervoltage-lockout circuit to prevent start-up• Wide PWM Frequency: Fixed 350 kHz, 550 kHz, until the input voltage reaches3V; an internally andor Adjustable 280 kHzto 700 kHz externally set slow-start circuit to limit in-rush Load Protectedby Peak Current Limit and currents; and a power good output useful for
