Part Number: LM26003 Hello
My customer designed inverting circuit using LM26003.
VIIN : +15V
VOUT : -12V
However, the maximum VBIAS voltage is 10V. Is it available to configure the circuit as shown below?
Best regards.
Part Number: LM26003 We are using mentioned device (LM26003) in one of our designs.
We would like to get the schematic reviewed before we move forward for manufacturing.
Below are the some parameters -
Max output current required: 2A

This is a 38V part. It shouldn't be damaged by 24V input voltage. Could you capture the waveform of input voltage and input current when the part is powered up? Depends on the layout, there could be large current spikes at the input side when it is charging…
Other Parts Discussed in Thread: LM26003 , LM26001 Hello,
One of my customer found the below behavior with LM26003 at light load. I guess the Frequency Foldback is wroking here. However, there are a lot of things unexplained. Please make an answer…
Please check the ON time of the switch tripped Tonmin condition or not. With higher Vin, Ton will reduce, and it may enter Tonmin condition. At Tonmin condition, Vout will drift up without any action, and it may trigger Sleep mode.
Hi Sergio,
Because the LM26003 is a non synchronous device it doesn't have what I would call a true Forced PWM operation as the inductor current can never go negative because of the external catch diode. The FPWM mode on the 26003 basically disables…
Other Parts Discussed in Thread: LM26003 I would like to confirm equations for LM26003.
- 1.33 for equation (23)
- 0.095 and 0.0065 for (24)
- 9.2*10^-9 for (25)
Are they constant values, are't they?
If they are not, do you have max/min values…
Other Parts Discussed in Thread: LM26003 I would like to confirm the damping resister for LM26003.
The custmer want to reduce the noise and will try to add the damping resister between Boot pin and thr capacitor.
Could you please teach the maximun…
Other Parts Discussed in Thread: LM26003 I would like to confirm the design of via hole for LM26003.
In the datasheet, there is the recommendation for via hole diametor of 0.3mm, but is not the recommendation for via arrangement (location).
Could…
