Part Number: SIMPLESWITCHER-COMPONENT-CALC We are planning to buy bulk quantity of the below mentioned parts for our projects. So, I need few details about it, please explain in detail.
1. How much area is required to store 9000 quantities of the part…
Part Number: SIMPLESWITCHER-COMPONENT-CALC Other Parts Discussed in Thread: LM2678 , LM2677 , LM73605 Tool/software: WEBENCH® Design Tools Hello,
I am a beginner in power management design. I have a requirement of DC 5V, 5A power supply with the input of…
Hello Takashi,
please use the LM5143 Design calculator and input your spec requirements. the design calculator will make component value suggestions based off of your inputs.

Hi, the efficiency results in the datasheet are based on our analysis on our EVM. The efficiency results are greatly influenced by the input and ouput voltages and currents and the passive components used such as FETs, inductors, capacitors etc. The 96…
Hello Sandeep,
You can with careful design considerations and with thermal management. I encourage you to use the calculator, link below.

Hi Mani,
Optionally as well, At the output you can implement an LC filter with a cutoff frequency of 20kHz to attenuate switching and cut high frequency noise. You can use this calculator to determine component values ( https://www.ti.com/tool/LCFILTER…
Hello,
For your design, a minimum of 2.2uF of input capacitance is required. The output capacitance is also too low. Try using two, 22uF output capacitors and make sure they are properly rated for the output voltage to account for capacitor de-rating…

Hi,
Please find attached a calculator for DRV3901-Q1 VREG Capacitors.
The other components requirement is provided in the datasheet under the external component section.
Thanks,

Hi Joscha,
the LM51772 will fit very well but input range is limited to 55V. The LM5177 can be used as well which will also allow higher input voltages but for that device the output voltage control needs to be done externally.
Due the the large about…
Winnie,
From a first look your schematic looks good.
Maybe the MOSFET only being 3mm x 3mm might get thermally warm, consider the power loss and heat management of those components.
Please double check your component values with the quickstart calculator…
