Part Number: LM2734 Hello,
I have a problem with the LM2734. I try to have Vout = 2V5 with Vin = 3V3 and the result is the following:
As you can see, the Vout (2V5, in yellow) is not stable as it should.
The schematics and the routing are:
Do you…
Part Number: LM2734 Hi,
I'm using LM2734 to design a power supply. The input voltage is 9V and the output voltage is 3.3V. When there is no any load, the output voltage is 3.3V. But when I connect 3 LEDs (about 10mA) to the output, the output voltage…
Part Number: LM2734 Hi,
I recommend TI's LM2734YQMKE/NOPB to my customer who is using Microchip's MCP16301T-E/CH for their application.
Below is their schematic, and they cannot change anything around the device now.
Please let me know if we…
Other Parts Discussed in Thread: LM2734 , LM3668 I would like to to review my LM2734 Schematic and PCB Layout to go for prototype testing.
My doubts are, Enable pin i directly connected to VIN. i think its always enabled. and My requirements here is 5V…
Other Parts Discussed in Thread: LM2734 I have a customer that is failing Class B FCC , Radiated EMI by 5 dB, and it appears to be coming from the LM2734. Vin = 12V, Vout =2.5V, Iout 800mA. Boost voltage is 5V from another source. The layout is good, Inductor…
Other Parts Discussed in Thread: LM2734 I am using the LM2734ZMK for converting 7-13V battery voltage to 3.3V for powering a microcontroller. When I power my board with a lab power supply (with fairly long wires), everything works as expected. However…
1. What is V(En) signal is it the output of a LDO, can you add that in your drawings? Ven is signal to supplies for power up sequence
2. What is the trip point of Supervisor IC? 12 V the threshold.
3. In your simulation what is the voltage on V3.3Vfilt…
Using LM2734ZMK to provide an output typically 5.8V (6V max with tolerances over temp).
Datasheet specifies max voltage on BOOST should be 5.5V if using feedback diode into BOOST.
Our diode has a Vf=0.6V. Can I actually add 0.6V to 5.5V = 6.1V and use…
