Product Summary
The TPS54312PWP is a low-input-voltage high-output-current synchronous-buck PWM converter which 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 3 V; an internally and externally set slow-start circuit of the TPS54312PWP to limit in-rush currents; and a power good output useful for processor/logic reset, fault signaling, and supply sequencing.
