The TPS55386EVM-363 is an evaluation module for TPS55383 dual non synchronous buck converter providing fixed 5.0V and 3.3V output at up to 3A each from a 12V input bus. The evaluation module is designed to start up from a single supply, so no additional bias voltage is required for start up. The evaluation module uses the TPS55386 600KHz Dual Non Synchronous Buck Converter with integral high side FET. The TPS55386EVM-363 is designed to use a regulated 12V (+10% /-20%) bus to produce two regulated power rails, 5.0V and 3.3V at up to 3A of load current each. The evaluation module is designed to demonstrate the TPS55386 in a typical 12V bus system while providing a number of test points to evaluate the performance of the TPS55386 in a given application. The evaluation module can be modified to other input or output voltages by changing some of the components.
● 12V +10% /-20% input range
● 5.0V and 3.3V fixed output voltage, adjustable with resistor change
● 3A DC Steady State output current (3A Peak)
● 600KHz switching frequency (Fixed by TPS55386)
● Internal switching MOSFET and external rectifier diode
● Double sided two active layer PCB with all components on top side
● Active converter area of less than 2.5 square inch < 1.15" X 2.15"
● Convenient test points for probing switching waveforms and non invasive loop response testing
