  The TJ2161 is a synchronous buck converter with an input voltage range of 2.5V to 6V. The device has an integrated 85mΩ high-side and 55mΩ low-side MOSFET switches (in case of TJ2161GSF8) that provide 2A of continuous load current with excellent load and line regulation. The output voltage can be regulated as low as 0.6V.
Adaptive 0n-time control scheme 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 TJ2161 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 TJ2161 is available in TOST23-8, SOP8, and SOP-8 exposed thermal pad packages.
