TPS61169: TPS61169 thermal issue

Part Number: TPS61169
Other Parts Discussed in Thread: TPS61165

Hi 

We need a DCDC 5V input and output 18V/260mA for LED driver, Now we use TPS61169DCKR but the temperature is too high when 5V input and output 18V/260mA, May be TPS61169 package is smaller, Is there any other suitable Chip that can replace this?

Thank you

    Hi Jerry,
    The thermal dissipation is related with PCB design, have you tried increase the PCB copper? TPS61169 should have the capability in your application. You could give another try on TPS61165, which is bigger package.
