UC2854: Oscillator frequency at room temperature

Pol REYMOND

Part Number: UC2854

Hi team,

My customer has a question on the oscillator frequency.

In the datasheet, there is a min/max value that is given at T=[-40;+85degC].

Do we have a min/max value only at 25degC?

Thanks in advance for your feedback.

Doc2.docxHello Pol,

The frequency range for the UC2854 is not specified at 25 deg C.

However are you sure thatit is not the UC285A or UC2854B that you are interested in ?

These are newer parts with significant changes from the older UC2854.

The frequency range for these parts is specified in Figure 7 of the data sheet and attached.

It has a frequency range from about 10kHz to 800kHz

Regards

John
