TPS61500: COMPENSATION CIRCUIT

Marco Dori

Part Number: TPS61500

I need some reference document to calculate the compensation circuit to attach at TPS61500 COMP pin. I coudn't find any document/tools regarding this pn and i need support to finish the pcb.

Thank you,

Marco

Hi Macro,
What's your detail application? And could you share me your circuit and some detail parameters? Usually it only nead a capacitor for this pin. 470nF is ok, have you met any question?
Regards
Sean

Dear Sean,

I've attached the schematic. The inductance value is 4.7 uH and i've prepared a circuit net for the compensation.

Hi Marco,
Your schematic seems ok, but as you have float the DIMC pin, it means thay you will use PWM signal on EN pin, so why you use the R2 pull up to VIN? I think you'd better remove this resistor.
