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-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.

The customer try to use LM53603EVM as the following condition. Vin = 5.8V Vout = 5.0V Iout…
Part Number: LM53603 Other Parts Discussed in Thread: LM43603 , LM46002 Hi Team,
My customer got a LM53603 EVM and have a question related to switching frequency.
Customer changed the Vo voltage to 8V on the EVM, the load current is around 2A. When he…
Part Number: LM53603 My customer is very interested in the LM53603. They would like to simulate the device behavior by the simulation tool of the PLECS. Thus here are some questions.
1. What's the VF value on the body diode of low side MOSFET at 55degree…
