Part Number: LM43603-Q1 Hi,
LM43603-Q1 is designed with input voltage range is from 9V to 36V and output is 5V in my customer's board.
RT pin of LM43603-Q1 is connected with a resistor to make 990KHz switching frequency.
The resistor value is 40…
Part Number: LM43603-Q1 Dear TI
I am thinking of replacing "LM43603PWPR" with "LM43603AQPWPTQ1".
Please answer the following two points.
(1) "LM43603AQPWPTQ1" is an in-vehicle grade product of "LM43603PWPR", and can it be considered that the…
Part Number: LM43603-Q1 PFA the Schematics
Input Voltage => +12V
Desired Output Voltage => -12V
Current Voltage observed => -8.99V
Output Current will be less than 0.5 amps
What changes will be required to achieve -12V. Most the values have…
Part Number: LM43603-Q1 Hi
My customer applied LM43603-Q1.
QUESTION :
Problems that can occur if PIN 15/16 (PGND) pin is not connected to GND.
Other AGND and PAD pins are tied to GND.

Part Number: LM43603-Q1 Other Parts Discussed in Thread: LM43603 Hello,
We use LM43603 as buck +24V => +13V with a very large capacitor loads (4700µF//4700µF). PGOOD is left floating .
I would like to know if PGOOD pin enable Hiccup protection (it…
Part Number: LM43603-Q1 Hi team
I don't check Tss maximum value of the LM43603-Q1 as the below.
If I don't apply Css, what is the maximum value of Tss?
Part Number: LM43603-Q1
HI Team
If the bottom pad of the LM43603-Q1 is not soldered properly, it is found that the output voltage is abnormal.
We have designed six vias in the bottom pad as shown in the datasheet.
However, in the SMT process…
Part Number: LM43603-Q1 Hi team.
My customer ask to me about output voltage level before Hiccup mode operation.
Do you have data on the minimum voltage to enter hiccup mode?
And are there test datas for over current limit?
If you have the above…
