Part Number: TPS40090EVM-002 hi,
I use the TPS40090EVM-002.
I want to adjust to the 2-phase, but it's not work.
How do i setup the EVM?
like CS2, PWM4 or any pin should to be floating, vcc, gnd or resistance to gnd?
Any reference scheme to offer…

Part Number: TPS40090 Hi Ti experts,
I want to refer to the project files(schematic/PCB document and BOM) of TPS40090EVM-002.
I can not find it at the bottom of the website . So could you send me the project documents.
Thx.
Hello Jaejeong,
TPS40090EVM-001 is configured for 4 phase operation only. TPS40090EVM-002 can be configured to 2-phase, 3-phase, or 4-phase operation, as seen on page 4 of the TPS40090EVM-002 User Guide.

Hi Qian,
1. Do you know why fph need to power up by -1.024?
In the TPS40090EVM-002 design guide, the frequency set up for each phase is 420kHz and Rt is calculated to be 65.8kOhm,
Do you able to get it by plucking this value in the given formula…
