TPS56637에 대한 설명
The TPS56637 is a high efficiency, high-voltage input, easy-to-use synchronous buck converter with integrated MOSFETs.
With the wide operating input voltage range of 4.5 V to 28 V, the TPS56637 is ideally suited for systems powered from 12-V, 19-V, 24-V power-bus rails. It supports up to 6-A continuous output current at output voltages between 0.6 V and 13 V.
The TPS56637 uses DCAP3™ control mode to provide fast transient response, good line and load regulation, no requirement for external compensation, and supports low equivalent series resistance (ESR) output capacitors such as POSCAP and MLCC.
The TPS56637 has both FCCM and Eco-mode™ operation modes for selection at light-load condition through configuration of MODE pin. To attain high efficiency at light load, Eco-mode™ could be selected. To support tight output voltage ripple requirement, FCCM could be selected.
The TPS56637 provides complete non-latched OV (Over-voltage), UV (Under-voltage), OC (Over-current), OT (Over-temperature) and UVLO (Under-voltage lock-out) protections combined with power good indicator and output discharge function features.
The TPS56637 is available in a 10-pin 3.0-mm x 3.0-mm HotRod™ QFN package and the junction temperature is specified from –40°C to 150°C.
