Part Number: ADS9226 Hello, I designed the circuit using ADS9226, with AVDD at 5V and DVDD at 3.3V. I inputted REFIN at 2.5V, but measured the voltage on REFP_A and REFP_B to be 4.3V. According to the datasheet, REFP_A and REFP_B are the buffer outputs…
这可能与当初EVM设计时，设定的典型值有关。并不是特定的。
下面是我找到的一些信息。
I did not personally design that EVM, but it is not uncommon to have restricted input voltage range. In this particular case, it has to do with the external UVLO set by R4 and R5. The typical start voltage is…
Part Number: LM62460 Other Parts Discussed in Thread: LM61480 Hi:
I used two LM62460 / LM61480 buck ICs for 25V to 12V and 25V to 18V；
The 25V to 12V circuit often burned out in input pin（VIN1&VIN2）when IC powered on.The 25V to 12V circuit had never happened…
Other Parts Discussed in Thread: UCC28070 We need to design a 3000W output power. The main input is 230V. It is going to be use in the BLDC pump. The DC bus is 390V. What kind of PFC control IC is recommended and any design recommendation? Thanks
Part Number: BQ25750 Hi all,
I'm using BQ25750 to design a MPPT Charger for Li-Battery. My verification board testing environment is as follows:
The VAC interface is powered by an adjustable switch power supply, with a voltage range within the VAC…
Part Number: TPS65185
VGL issue IC Name: TPS651851 Application: 13.3" e-paper Question: I'm designing a power supply board for e-paper. The voltage input/output is as follows: VIN: 5V LDO1 (VPOS): +15V LDO2 (VNEG): -15V CP1 (VDDH): +25V CP2 (VGL): -…
1. The output should be regulated - it's just the inductor current waveform that will change.
All protections should still be active (Overcurrent, overtemperature, etc)
2. Yes
3. For stability, I would recommend you use the quick start calculator. As…
Part Number: PROCESSOR-SDK-AM62X
In ti-processor-sdk-linux-rt-am62xx-evm-10.01.10.04，I want to use the CJC8990 as the audio codec on the AM62X chip, but the following error occurred when I was using it.
