Dual Input Bus (3.3, 2.5V) 9A Output Synchronous Buck Converter

As a member of the SWIFT family of DC/DC Regulators the TPS54974 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 that enables maximum performance under transient conditions and flexibility in choosing the output Filter L and C components; an undervoltage-lockout circuit to prevent start-up until the VIN 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 TPS54974 is available in a thermally enhanced 28-pin TSSOP (PWP) PowerPAD? package, which eliminates bulky heatsinks.
