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-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 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 I'm having problems with a design using the LM43603. I'm using several of them with different output voltage. But for this case I will just mention specs: Vout 3.3V, 1.0 A. Vin 10-33V I'm using the recommended approach in the…
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…
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 been…
Part Number: LM43603 Dear e2e support,
My customer is facing an issue on multiple boards, for a 12V --> 5V@1A application
After 3 to 4 days in continuous test, the DC/DC doesn't restart
The VCC gives a 2.4V only.
If an external 3.3V is applied…
Part Number: LM43603 Hi everyone,
I'm following the datasheet and trying to calcualte Cff value for LM43603. I'm following section 8 as a design exmaple.
Crossover frequency, fx, calculated using equation 21 and given Vout = 3.3V and Cout = 150uF…
Part Number: LM43603
Hi Team:
Issue: the circuit could run as normal, but once hand touch with some sensitive area on the board, the outout disapear and sometime could revovery when moving the connection and occationally this cause short between the output…
Part Number: LM43603 Hi,
I am using an LM43603 to go 12V to 3.3V at light loads, I can see the bottom FET is turning off for part of the cycle, when it turns off there switch node then rings for a number of cycles, peak voltage is a significant percentage…
