Part Number: TPS65263-1Q1

Hello,

My customer has question of switching frequency of TPS65263-1Q1.

In data sheets, it is written about SW frequency min 430kHz typ 500kHz max 560kHz.

Can they think it's accuracy -14%~+12%, when the setting of SW frequency by resistor is set to typ 2.1MHz.

Regards,

Hi,

The number may be a little different from the accuracy when set to 500kHz, but we don't have the number either...

Hello, 　Sam-san,

They use that tps65263-1Q1 for HUD.
So, it must be used avoiding the under 1.6MHz.

Roughly it is OK, is within ±20% ?
If not , try changing the device.

Taichi

Hi Taichi,

Yes, set the switching frequency at 2.1MHz and the part will definitely work above 1.6MHz, althougth there may be some variation.
Also, please use higher accuracy resistor to set the frequency. It's also helpful.

Regards,
Sam
