LM2650: Resistors and Capacitor

Mark Philip Felipe

Part Number: LM2650
Other Parts Discussed in Thread: TPS629210-Q1, TPS629210,

Hi Team, Is it safe to use the same component values from Table 3 (3.3 V output) but adjust the R1 and R2 values to get a different output voltage?

For the input/output capacitors, should I put those in parallel?

Thank you.

Hi Mark,

It is safe to use table 3 with adjusting R1/R2 to get a different output voltage. You can parallel the input/output caps.

LM2650 is old device with voltage mode control. What is your application? We have new DC-DC converter TPS629210-Q1(automotive) and TPS629210(commercial) with optimized performance at smallest package.

The device and EVM /EVM user's guide are available on TI website. Please review the datasheet and see if it fits your application.

Thanks,

Nancy
