The TPS54202DDCT is a 4.5V to 28V input, 2A output, EMI friendly synchronous step down converter in 6 pin SOT package. This device includes two integrated switching FETs, internal loop compensation and 5ms internal soft start to reduce component count. It achieves the high power density and offers small footprint on PCB. Advanced Eco-mode implementation maximizes the light load efficiency and reduces the power loss. The frequency spread spectrum operation is introduced for EMI reduction. Cycle by cycle current limit in both high side MOSFET protects the converter in over load condition and is enhanced by a low side MOSFET freewheeling current limit which prevents current runaway. Hiccup mode protection will be triggered if over current condition has persisted for longer than the present time. It is used in 12V, 24V distributed power-bus supply, white goods, STB, DTV and printer.
