TEXAS INSTRUMENTS TPS54314PWP 直流-直流开关降压, 逐步递降稳压器, 可调, 3V-6V输入, 1.8V/3A输出, 550kHz, HTSSOP-20
The is a synchronous buck PWM Switcher with integrated FETs SWIFT™. The 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. provides evaluation modules and the SWIFT™ designer software tool to aid in quickly achieving high-performance power supply designs to meet aggressive equipment development cycles.
