I use LTM8063 to get -10V. today i found my LTM8063 can't output -10V.
After check, i found the FB pin is short with GND pin.
i remove all res and cap around LTM8063, then FB is still short with GND pin.
the input is +12V.
the sch is like the typical…
The LTM8063 is not limited by max duty cycle, it is limited by minimum off-time. If the off-time approaches the minimum off-time of 90ns, the part will lower its frequency.
At low frequencies, the LTM8063 can reach near 100% duty cycle.
I am working on a design with the LTM8063 on DC2494 evaluation board. I noticed that the ev board has a 100k pull-up to Vout since the LTM8063 PG is an open collector output. The PG signal goes to an input pin of an ATF1508AS CPLD, which…
Hi support team.
I will use LTM8063 as a negative converter.
Schematic is very similar to datasheet p.20(-5V circuit),and PG pin is pulled up to external +2.5V.
However ,in this case PG pin low voltage goes -5V level.
So I want this [-5V - +2.5V] to…
