DESCRIPTION
  The TJ54336 is a synchronous buck converter with an input voltage range of 4.75V to 23V. The device has an integrated 100mΩ high-side and 85mΩ low-side MOSFET switches that provide 3A of continuous load current and eliminates the need for an external diode which reduces component count.
Current mode control provided fast transient response, cycle-by-cycle current limit and excellent output voltage regulation. It is stable with low ESR output ceramic capacitors. This device provides accurate regulation for a variety of loads with a well-regulated voltage reference.
Efficiency is maximized by integrated switches, low IQ, and automatic pulse skipping at light loads.
The TJ54336 is equipped with adjustable soft start and protection functions for various conditions such as over voltage, under voltage, over current, short circuit and over temperature.
The TJ54336 is available in SOP-8 exposed thermal pad package.
