TPS65131-Q1: when output is positive/negative 6.2V, design our HW sch with correct RC

April Jiang

Part Number: TPS65131-Q1

In the datasheet, there's only RC recommendation for Vout= 10V , when Vout is 6.2V , what the RC should be? if there's any risk when we choose the same RC value (output voltage = 10V)?

Hello April,

Section 9.2.1.2 on page 13 of the data sheet gives out simple formulae for calculating design values. The only values that need to be calculated are R1, R2, R3, R4, C9 and C10. Based on design requirements in the datasheet and VPOS/VNEG set voltages of +/-6.2V, I calculated following values. Please choose the closest standard available component values for your design.

R1=534.4K

R2=130K

R3=619.4K

R4=121.2K

C9=12.7pF

C10=12.1pF

Kind Regards,

Liaqat
