TPS54312 Overview
Key Specifications
Package: HTSSOP EP
Pins: 20
Operating Voltage: 6 V
Min Voltage (typical range): 3 V
Description
As members of the SWIFT™ family of DC - DC regulators, the TPS54311, TPS54312, TPS54313, TPS54314, TPS54315 and TPS54316 low-inputvoltage high-outputcurrent synchronous-buck PWM converters integrate 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 to limit in-rush currents; and a powergood output useful for processor/logic reset, fault signaling, and supply sequencing.
