Tokmas TPS54560DDAR

The TPS54560D is 5A buck converter with wide input voltage, ranging from 4.5V to 60V, which integrates an 80mΩ high-side MOSFET. The TPS54560D, adopting the peak current mode control, supports the Pulse Skipping Modulation (PSM) which assists the converter on achieving high efficiency at light load or standby condition. The TPS54560D features programmable switching frequency from 100kHz to 1.2MHz with an external resistor, which provides the flexibility to optimize either efficiency or external component size. The converter supports external clock synchronization with a frequency band from 100kHz to 1.2MHz. The TPS54560D allows power conversion from high input voltage to low output voltage with a minimum 130ns on-time of highside MOSFET. The device offers fixed 4ms soft start to prevent inrush current during the startup of output voltage ramping. The TPS54560D features external loop compensation to provide the flexibility to optimize either loop stability or loop response. The TPS54560D provides cycle-by-cycle current limit, thermal shutdown protection, output over-voltage protection and input voltage under-voltage protection. The device is available in an 8-pin ESOP-8 package.
