Description

The TPS54302 device is a 4.5V to 28V input voltage

range, 3A synchronous buck converter. The device

includes two integrated switching FETs, internal loop

compensation, and 5ms internal soft start to reduce

component count.

By integrating the MOSFETs and employing the

SOT-23 package, the TPS54302 device 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.
