Forum Post: BQ2002F as a single 9V battery charger building block
Dear TI support staff,I'm designing a single Ni-MH 9V battery charger and after searching and comparing PNs I came across the BQ2002F which seems to fit the design specs and budget. However I'm not...

Hello Duncan,Webench actually calculates the power dissipation in the FET and the juction temperature of the FET at the worst conditions and picks the FET only if it passes those checks. Therefore if...

Alright, this is all good information. Thank you all so far! My next problem seems to be output current. If I'm still allowed to post.....I know the max voltage I want (9), and a set resistance on load...
View ArticleForum Post: RE: Varying the Vout on the LM3668
Hi Bill, Jeff has it right. The Vfb voltage is regulated to +/-3% accuracy, to the 4.5V can vary by +/-135mV. If I understand correctly, you want to create these worst case condition via external...

AnandYour calculation to change the resistor to 203.5k is correct and you should use the next standard value greater than this in the circuit. That would be 205 kohm.The device offers x10 mode to...

HarryThis looks like a tools mismatch with the device. Have you tried rerunning the setup program to see if it was corrupted? Have you seen it occur on more than one EVM? RegardsTom

KonstantinIf the addressing and PEC are set correctly, then I would use an oscilloscope or waveform analyzer to inspect the data from the MCU. Compare them to the same commands from the EV2300. Tom

View ArticleForum Post: RE: 3.2V to variable Vout converter needed
That can require a lot of current in the switch for a boost converter. If you want to do a buck regualtore say from 12 or 15 V supply, TPS54020 (integrated FETs) or TPS40170 ( controller with external...
