TPS54010PWPRG4

输入电压为 3V 至 4V 的 14A 同步降压转换器 28-HTSSOP -40 to 85

DESCRIPON

As a member of the SWIFT™ family of dc/dc regulators, the TPS54010 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 pre- vent start-up until the VIN input voltage reaches 3 V; an internally and externally set slowstart circuit to limit

in-rush currents; and a power-good output useful for processor/logic reset, fault signaling, and supply sequencing.

FEATURES

• Separate Low-Voltage Power Bus

• 8-mΩ MOSFET Switches for High Efficiency at 14-A Continuous Output

• Adjustable Output Voltage Down to 0.9 V

• Externally Compensated With 1% Internal Reference Accuracy

• Fast Transient Response

• Wide PWM Frequency: Adjustable 280 kHz to 700 kHz

• Load Protected by Peak Current Limit and Thermal Shutdown

• Integrated Solution Reduces Board Area and Total Cost
