Part Number: TPS53219A Tool/software: Hi
As Figure 18 Typical Application Circuit shows, L1 = 0.44uH, COUT = 330uF x 2
I use the equation (9) with the following value for inductance calculation
IOUT (max) = 25A, FSW = 500kHz, VIN(max) = 18V, VOUT = 1…
Part Number: TPS53219A Tool/software: Hello,
Our customer has a question if TPS53219A build in pull down function on DRVH, DRVL in order to keep Low state before power up, e.g. pull down resistor, pull down transistor.
Could you please let us know if…
Part Number: TPS53219A Hi
Customer have two question about TPS53219A setting and could you help to check them ,thanks.
1. VDD Pin suggest connected to which voltage level if 5V cannot be used, use ADAPTER , 20V is available ? 2. Whether the VDRV pin can…
Part Number: TPS53219A Hi Team！
There is a technique question.
When the device go into Hiccup mode, it would try to turn on the fet. I wanted to know how to determine the conduction time(ton).
Part Number: TPS53219A Background :
Customer shared : Set shutdown during working, display abnormal. Swap test completed as below. customer chamber reproducing evaluation – IC shutdown occurred since OTP(Over Temperature Protection) working after 1 hour…
Thank you for your suggestion. I fully agree with you that an ambient temperature should be a test condition, not measured on the board. In this customer case, even though he does not disclose everything e.g. schematics, PCB layout, thermal source, I suppose…
Part Number: TPS53219A Hello,
Our customer has a question if TPS53219A works abnormally when he placed 1uF ceramic capacitor on TRIP to GND for noise suppression.
Best regards,
Part Number: TPS53219A Hello,
Our customer has a question if TPS53219A soft start time is able to adjust to intermediate time such as 1.0ms by connecting 82k-ohm on MODE pin. Would you please let him know if TPS53219A can support such kind of soft start…
Part Number: TPS53219A Hi Expert,
