Part Number: BQ76940 Good day, I had just finished soldering components into my board ( https://e2e.ti.com/support/power-management/f/196/t/771358 ), and would like to ask if there's anything I should take into account before actually powering up my board…
Hi Pratik,
The droop is implemented by summing a signal that is proportional to the inverse of the output current to the feedback reference (through R20 in image below.) This requires sensing the output current. If you are not already sensing the output…
Hello Arumugam,
I reviewed the power tip article and I understand the basic concept. The circuit as it is shown here, will work for duty cycles of 50% or less.
When the driver is on, DRV is driven close to VDD on the dot of the transformer, Q2 device…
Hello Gary,
Yes, I agree that the 100KHz entry in the table does not match with the curve. It is quite likely a typo. I do not see too much wrong in the PSRR plot you have generated. It is not atypical to see ~3-4B of variation in PSRR from device to…
Part Number: THVD1450 I need some help. In a specific application, the THVD1450's drive strength is too powerful, which leads to fast edges and higher emissions.
Could you help list what steps can be taken to reduce emissions?
I know you could use…
USB Type-C™の電力供給（PD）標準では、1ポートあたり7.5W（5V、1.5A）～100W（20V、5A）の電力を見込んでいます。しかし、個々のシステムでは、使用できる入力電力に制限があります。複数のポートを持つシステムでは、各ポート間で電力をどのように割り当てればよいのでしょうか。
明白な電力共有方法の1つは、ポートごとの電力を制限して、合計の消費電力が入力電力制限を決して超えないようにすることです。しかしこの場合は、電力がポート間で分割されるため、システムに接続されたどのデバイスも…
