General Description

The TPS56339 is a 4.5-V to 24-V input voltage range, 3-A synchronous buck converter.

The device includes two integrated switching MOSFETs, internal loop compensation and 5-ms internal soft-start to reduce component count.

By employing the SOT-23 (6) package, the device achieves the high power density and offers small footprint on PCB.
