Part Number: LM43603-Q1 Other Parts Discussed in Thread: LM43603 , LM46002 We are having startup issue with using an LM43603 rather than a LM46002. Schematic below.
When the supply has around 6V to 8V at the input the output ripple is around 400mV. When…
Part Number: LM43603
I have made 2 PCBs with the same schematic shown but different layouts. One circuit works fine and the other has poor output voltage regulation.
On the one that has poor regulation, under no-load it outputs the desired voltgae (5…
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…
Part Number: LM43603 Hi TI Team,
I would like to check if this part is able to undergo the washing process (using DI water).
Please provide any relevant supporting document if possible.
Part Number: LM43603-Q1 Other Parts Discussed in Thread: LM43603 Hi Team, The datasheet shows the following. --------------------------------------------- LM43603A-Q1 version is optimized for PFM operation and recommended for new design. The device is pinto…
Part Number: LM43603 Hi Team,
Customer is having issue when using the LM43603 TINA-TI Transient Reference Design (snvm609 file) of LM43603. Below is the details.
I downloaded the snvem609.tsc ,this model can not do DC analyze, no output. I want to use this…
Part Number: LM43603 Hello All
In a no load condition the output voltage in the circuit below is 3.3VDC. With 2.5A load the voltage drops to about 3.0V.
If I increase the inductor value to 6.8uH the voltage drops even more. With a 2.2uH inductor it works…
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 40.2Kohm…
Part Number: LM43603 Hi,
I am considering using the LM43603 device. I would like to ask you about Bootstrap capacitors. The data sheet states that a capacitor with a withstand voltage of 6.3V or higher and a capacity of 0.47uF should be used. In EVM, 25V…
