• LTM8063 Faliure cause

    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…

  • RE: Question about LTM8063

    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.

  • LTM8063失效问题请教

    我使用LTM8063来产生-10V电压。输入为+12V。

    LTM8063产生-10V的电路参考手册第20页中产生-5V的接法。

    使用过程中负载电流小于100mA,周围无发热期间,器件本身也无明显发热。

    使用一段时间后发现LTM8063无法输出-10V,经检查FB管脚和GND管脚短路。

    将LTM8063外围阻容拆掉后,FB管脚仍然和GND短路。

    想咨询一下短路的可能原因。

  • LTM8063 on DC2494A ev board: PG pin pull-down

    Hi everyone,

    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…

  • LTM8063 PG pin level shift requirement when outputs negative

    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…
