TPS23753A: There are some needs for Cost Down about the Schematic Desig of TPS23753A and TPS23756

Part Number: TPS23753A
Other Parts Discussed in Thread: TPS23756, , TPS23755EVM-894, TPS23755

Hello sir,

Our customers are evaluating the TPS23753A and TPS23756. On the design of peripheral circuits, there are some needs for Cost Down.

Do you have some reference design or advises to help them to achive the needs of Cost Down, such as reducing components, replacement of inexpensive devices and so on.

Many thanks.

    Hi Kevin,

    What power level & output voltage are they targeting?

    We recommend that they take a look at TPS23755 & the associated TPS23755EVM-894 EVM for 12V/1A reference design. This PD controller eliminates the need for feedback circuits (due to primary side regulation), is diode rectified, & has Spread spectrum dithering with reduces the need for large common mode choke values if the customer needs to pass EMI.

    Thanks,

    Hi Tom,
    The input is 48V, and output is 12V.

    Our customer is evaluating the TPS23755 solution.
