Part Number: TPS40100TPS40100 芯片数据表无法查询到最小的输出建立时间;目前遇到一个问题，当在芯片ss （softstart）引脚对GND加100nF电容时，Vout建立时间约4ms;当将ss引脚对GND电容容量减小，例如47nF、10nF等值时，Vout建立时间仍然无法改变，想请教贵司是什么原因？

Part Number: PTH08T230W Other Parts Discussed in Thread: PTH08T220W , TPS40100 Tool/software: Hi,
We are utilizing the PTH08T230W power module, which is set to output 0.8V. When we measure the voltage at test point TP9, which is situated close to the…
Other Parts Discussed in Thread: TPS40100 Hi,
I'm using PTH04T241WAS as my MPC8548 PowerPC CPU core power supply. The input is 3.3V, and the output is 1.1V.
In the operation, when the output 1.1V ramps to 0.4V, we can find inrush current happens…

Other Parts Discussed in Thread: TPS40100 Hello,
I am the new guy to use the DC/DC converters. Here I need a DC/DC whose output voltage could be controlled on real-time, and also a DC/DC converter whose output current could be controlled. Could you…
Other Parts Discussed in Thread: TPS40211 , TPS40210 , TL431 , TPS40100 I am considering using the TPS40211 for a renewable energy application to charge a 48VDC battery from a lower voltage input source (10-40V). In order to limit the charge current,…
Ramgopal,
Your assessment of the bulk decoupling required is correct. You must calculate the required amount and validate it. The Hardware Design Guide (SPRABI2) discusses this calculation.
This bulk capacitance will affect the control loop on the…
SI,
Please see the attached presentation. It was originally prepared for the LM10010 which was later superceded by the LM10011 which has higher precision. Please also see the many E2E posts discussing the LM10011 and TPS56121 with C667x and C665x. …
