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…
Part Number: LM53603-Q1 Other Parts Discussed in Thread: LM53603 , LM53602 Hello,
I have question based on datasheet LM53603/602, there is a sync pin (input only) but are we capable to have a syncout too?
Meaning does the sync pin is dual function…
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…
Hello,
Yes, you bring up a good point. Since the LM53603 is a current mode control device, the inductor current will directly control the transition from PWM to PFM. When the inductor valley current reaches 0A, the device will transition from PWM to…
Part Number: LM53603-Q1 Hi All,
TI's recommended phase margin is 45 degrees. Is my understanding of this correct? Does this take into consideration variations of external parts, IC and temperature?
The evaluation result at low temperature was less…
Part Number: LM53603-Q1 Hi, team.
My customer requires the thermal model(pdml file) for LM536035QPWPRQ1 & LM536033QPWPRQ1 for FloTHERM tool.
Do you have the model filr(pdml) for them?
Best regards,
Hidekazu Someno
Part Number: LM53603-Q1 Other Parts Discussed in Thread: LM53603 Hi,
The datasheet have following comments;
"Under no conditions should the output voltage be allowed to fall below zero volts."
Is this comment(falling below zero volts) how condition…
Part Number: LM53603-Q1 Other Parts Discussed in Thread: LM536035EVM Hi all,
Please tell me the measurement method in Fig.4 in the data sheet.
Should I monitor the SW waveform?
This evaluation uses LM536035EVM. .

Part Number: LM53603-Q1 Hi,
The datasheet has following comment;
The maximum recommended output voltage is 6 V. An extended output voltage range to 10 V is possible with changes to the typical application schematic. Also, some system specifications…
Other Parts Discussed in Thread: LM53603-Q1 Hi Team
may i have your help to check the peak current of LM53603-Q1, as D/S described, the min is 4.5A, but as our measurement on EVM, the peak current is 3.8A only, which number is correct?
