LM5155-Q1: Roadmap for Low Vin to High Vout Boost DC/DC

Part Number: LM5155-Q1
Other Parts Discussed in Thread: LM5155, TL499A

Is there roadmap for below Boost DC/DC?

・Vin: 1.8V_min ~ 

    ⇒Supply power is 2~3 cell NiMH battery, 1.8V is minimum case with margin.

・Vout: 6V~28V

　⇒Vout is depend on customer end application

・Iout: 200mA

・Price required as low as possible.

・Application is consumer (It is OK to non-Q1 device)

I found only LM5155-Q1(Preview), but Price feel high.

If there no roadmap matched Boost DC/DC, please let me know RTM schedule for LM5155-Q1.

Best regards,

Satoshi

    Hi Satoshi,

    Thank you for considering TI product. You should contact the factory for a high volume price quote. By the way, the LM5155 cannot support your 1.8V during startup. It requires a min 2.97V to startup. It can go down to 1.5V once the VBIAS is >3.5V. We also have a controller TL499A that may meet your need. For roadmap devices, we cannot share in e2e. You may contact TI sales in your region.

    For the LM5155 Commercial, we are targeting RTM soon. For the automotive grade LM5155-Q1, the target is 2nd quarter of 2019.

    Again, thank you.

    Best Regards,
