Part Number: LM5030 Dear Mr.
Design is Vin=17-28V, Vout=250V, Iout=1A, Fsw=250kHz, LM5030
My push-pull transformer haven't enough output voltage and I going to use voltage doubling rectifier
It is working excellent with sinusoidal signal, but here…
Part Number: LM5030 Other Parts Discussed in Thread: TIDA-01352 Hi Expert
But I need to make some ultrasound application.
The spec of product is input voltage 12V, output voltage is +-100V , 50W.
The original design is for 24v input.
Part Number: LM5030 Other Parts Discussed in Thread: TIDA-01352 Dear mr.
1. I try to build power supply 400W, Vin=18V-29V to 300V with LM5030 and order for it planar transformer with next parameters: 500W, n=1:19, Lprimary1-3= 8.5uH (10kHz…
Part Number: LM5030 Good Day Sir/ Madam
For my push pull converter application I have selected LM5030 (VSSOP package).
The junction to ambient resistance is given as 158 degree c/W which I think is very high for my application. I wanted to do a power…
Part Number: LM5030 Dear mr.
I have a problem with bring up of PS , see sch.
Spec. Vin=17-27V, Vout=300V, Pout =400W
Voltage feedback is disconnected by removing R259 for simplification
I'm waiting to see about 50% PWM of MOSFET's control.
Part Number: LM5030 Hi team,
My customer uses LM5030 in their project(Vin=48V, Vout=210V/1A), could you please help check below questions?
1. What is the operating mode of the LM5030 at light load (or no load), is it a hiccup mode?
2. The power range recommended…
Part Number: LM5030 Hi,
Please explain, what minimum and maximum recommended range of frequency operation?
Into the datasheet(rev November 2015) page 6, I see "Frequency1 - 200kHz and Frequency2 - 600kHz",
Is 200kHz it minimum and 600kHz maximum…
Part Number: LM5030 In the data sheet for the LM5030 100-V Push-Pull Current Mode PWM Controller, November 2015 edition, Figure 14 is a partial PCB layout example -
In the PCB layout example, VFB is grounded (which takes the error amplifier out of the…
Part Number: LM5030 Hi, I was designing dc-dc converter using LM5030 , the output specifications are
Output 1: 13V, 4.9A
Output 2: 13V, 3.8 A
the primary input voltage is 74V and the estimated primary continuous current is 4.3A
so for overcurrent protection…
