TPS54202DDCR

The TPS54202 is a 4.5-V to 28-V input voltage
range, 2-A synchronous buck converter. The device
includes two integrated switching FETs, internal loop
compensation and 5-ms internal soft start to reduce
component count.
By integrating the MOSFETs and employing the
SOT-23 package, the TPS54202 achieves the high
power density and offers a small footprint on the 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 an overload condition and
is enhanced by a low-side MOSFET freewheeling
current limit which prevents current runaway. Hiccup
mode protection is triggered if the overcurrent
condition has persisted for longer than the present
time.
