The TPS54317RHFT is a 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 provides high performance under transient conditions, an undervoltage-lockout circuit to prevent start-up until the input voltage reaches 3V, an internally and externally set slow-start circuit to limit in-rush currents and a power good output useful for processor/logic reset, fault signalling and supply sequencing.
Externally compensated for design flexibility
Fast transient response
Load protected by peak current limit and thermal shutdown
