Part Number: LM53603 Other Parts Discussed in Thread: TPS2549 Hi,
We are working with the TPS2549Q1EVM eval board (USB Charge Port). The design uses the LM53603AQPWPRQ1 Switching power supply. The schematic indicates an input voltage range of 7V-18V. That…
Part Number: LM53603 I use the LM53603 to supply Vout=5V to my circuit. I would like to have the option to feed 5V in from a secondary source while the LM53603 input can be 12V or floating.
The datasheet says "Don't: Allow the output voltage to exceed…
Part Number: LM53603 Other Parts Discussed in Thread: TPS61022 Hi team,
My customer wants to use LM53603 as a main power supply and TPS61022 as a backup power supply from a battery. There is diagram of the design:
Switching from main power supply to…
Part Number: LM53603-Q1 I am using the LM53603-Q1 voltage regulator chip with a fixed output voltage of 3.3V and 2.2A max output current. The part works great with an input voltage of 25V but I need it to work down to about 4.5V. The datasheet says it…
Part Number: LM53603-Q1
Dear all
When I test the load capacity of the device, there is a question about it, as below, my design is according to EVM, Vout set 5V.
1. When my load is 1.4A, then Vin power on, but there is not any output, Why ? the below…
Part Number: LM53603-Q1 Other Parts Discussed in Thread: LM53603 Hi All,
My customer is using LM53603-Q1 in their T-BOX product and meet EMC issue, so a 10R serial resister was added with Cboot to solve EMC issue. But after adding this resister, we found…
Part Number: LM53603 Tool/software: WEBENCH® Design Tools I opened a Webench design for it. Cin in Webench is 4.7uF. However, according to the datasheet, the minimum recommended input capacitance is 2x10uF.

Part Number: LM53603-Q1 Hello
We are using LM536035 as a 12V to 5V power supply.When we use the reference design,the DCDC works fine,but the EMC parameters are not good in frequency multiplication.
When we change the value of output inductor,the EMC…
Part Number: LM53603 Hello team,
I have a similar question as below.
