Vout Accuracy of TPS62560

Other Parts Discussed in Thread: TPS62560, TLV62565


Dear All,

Would you provide us the specification data of TPS62560?
Please give us the data which can show accuracy of TPS62560's Vout, at following situation.
Vin ：3.3V
Vout ：1.2V
Iout ：300mA

It is written as "Output Voltage Accuracy in PWM Mode ±2.5%" to a datasheet of TPS62560.
However, our customer is interested in a competing IC of "Output Voltage Accuracy ±2.0%".
Will you provide to us measurement data of this IC's several lots?

Best Regards,
Tsuguhiko Asai

    i'm not sure why you want to get the measurement data. could you share more detail about the customer's application? based on the Vin and output condition, there are other devices with better PWM output voltage accuracy. thanks

    Dear Jasper-San,

    Thank you for your kindly response.

    Sorry, we do not have details about customer's application.
    But, we add the situation of customer.
    We have already recommended to customer TLV62565 having higher output accuracy (±2.0%) than TPS62560.
    However, the customer wants to adopt TPS62560 because TPS62560 is lower price than TLV62565.
    Therefore, customer want to consider whether TPS62560 can be used.
    The reason why our customer wants data of the output voltage accuracy is the above.

    Best Regards,

    do you have the requirement of output accuracy? we only have FB reference voltage accuracy, not output voltage accuracy, you should also consider the accuracy of feedback resistor. and when considering the PFM mode, the FB accuracy would be -2.5%~3.5% for TPS62560, and -2%~3% for TLV62565. I'm not sure the customer have realize this behavior. 

    could you send me email?
