Hi, team,

I just need to confirm one thing with you.

What is the difference between TL2845B and TL2845? I did not find some difference from datasheet.

Thanks.

Hi Johnny

The TL284xB and TL384xB series are pin compatible with the standard TL284x and TL384x with the following improvements. The start-up current is specified to be 0.5 mA (max) (1mA on TL2845), while the oscillator discharge current is trimmed to 8.3 mA (typ), tighter tolerance on switching frequency for B version. In addition, during undervoltage lockout conditions, the output has a maximum saturation voltage of 1.2 V while sinking 10 mA (VCC = 5 V).

Regards

Peter
