The TPS40193 is a synchronous buck controller designed for input voltages ranging from 4.5V to 18V. It operates with a fixed switching frequency of 300 kHz, which allows for the use of smaller inductors and output capacitors, contributing to a compact power supply solution. The controller supports output currents of up to 20A and is capable of handling pre-biased outputs. Key features include three selectable thermally compensated short-circuit protection levels, hiccup restart from faults, and an internal 5V regulator. The device incorporates adaptive anti-cross conduction to prevent shoot-through current in the power FETs. It also features a power good output and a soft-start time of 4 ms to manage inrush current during startup. The TPS40193 is packaged in a 10-pin 3mm x 3mm VSON package, suitable for applications such as cable modems, digital set-top boxes, and entry-level servers.
