1 Description

The TPS53355EVM-743 is designed to use a regulated 12-V bus to produce a regulated 1.5-V output at

up to 30 A of load current. The TPS53355EVM-743 is designed to demonstrate the TPS53355 in a typical,

low-voltage application while providing a number of test points to evaluate the performance of the

TPS53355.

1.1 Typical Applications

• Server/storage

• Workstations and desktops

• Telecommunication infrastructure

1.2 Features

The TPS53355EVM-743 features:

• 30-Adc, steady-state output current

• Supports prebias output voltage start-up

• J5 for selectable switching frequency setting

• J4 for selectable soft-start time

• J2 for enable function

• J6 for auto-skip and forced CCM selection

• Convenient test points for probing critical waveforms
