Other Parts Discussed in Thread: PMP,
Hi,
I am considering the circuit of PMP 20183 using the LM 3481.
I assume the following specifications.
I calculated the peak current of the inductor (68 uH), but it flows about 1 A at the operating frequency 100 kHz.
I want to change the operating frequency to 208 kHz in order to reduce the size of the inductor
and set the peak current to about 500 mA. Attach the calculation result Excel.
Is this possible to change? If so, is there any other parts that change the constant?
(specification)
VIN: 10.8 V to 26.4 V
VOUT: 143 V to 166 V
IOUT: 10 mA (for laser diode)
(Inductor to be used)
SLF 7045 T - 680 MR 60 (TDK)
Best Regards,
