Part Number: LMR33640
Hi Team,
I am using the LMR33640 in an inverting buck boost configuration (as per datasheet reference design).
Design Details: Input Voltage: 10V DC Output Voltage: -5V DC Target Output Current: up to 1A Inductor: 10uH, 5A…
Part Number: LMR33640 Hello,
I want to generate -12V using the LMR33640. I built a PCB using the attached circuit diagram. U25 is an LMR33640. However, if U25 is installed, a short circuit occurs. Removing U25 works fine. Is there something wrong with…
Part Number: LMR33640 I'm using the LMR33640DDDAR with an op-amp as a virtual ground at the feedback voltage divider to create a programmable voltage regulator with Vs = 16 V and Ua = 8.5–14 V. Load: 0–3 A. L1 = 8.2 uH. Unfortunately, the voltage drops…
Part Number: LMR33640 Dear Team,
We are using the LMR33640ADDAR part in our device with a recommended output voltage of 12 V. Could you please clarify the expected output behavior if the input supply is reduced to 9 V? Specifically, we would like to…
Part Number: LMR33640 Other Parts Discussed in Thread: LMR38010 , LMR38020 Hello,
we are currently designing the power for a board where we need to generate -40V from a positive voltage. The current consumption will be around 30-40 mA. Ideally, we would…
Part Number: LMR33640
Tool/software:
Hi,
We are currently designing a negative power supply using the TI LMR33640, and we would like to confirm the appropriate voltage levels for the EN pin when used in an inverting buck-boost configuration. We…
Part Number: LMR33640 Dear Team,
This is Banupriya from iWave Systems. We are using the LMR33640ADDAR in our device to generate a fixed 5 V output voltage. And additionally we require the fixed 12 V output voltage (11.4 V is also acceptable) with 12…
Part Number: LMR33640 I've designed a circuit that converts a +8.8V positive voltage supply to a -6.0V negative voltage supply. I have some questions.
1. Is it possible to supply 4A of negative voltage?
2. Are there any issues with the current circuit…
