• ADP2441 Minimum ON Time

    What is the minimum ON time of ADP2441?

     

    The maximum operating frequency is limited by the minimum on-time and the
    required duty cycle.  ADP2441 has minimum on time of 50ns.  Low minimum on-time
    makes ADP2441 suitable for applications…

  • ADP2441 Floating Pins

    Which of the following ADP2441 pins can be left floating?

    PGOOD
    FREQ
    SS/TRK

     

    The PGOOD pin can be left floating if not used.

    The ADP2441 requires frequency resistor to be set in order to calculate
    switching frequency. It…
  • ADP2441 Precharge Startup

    Does ADP2441 support a precharge startup?

     

    Yes, ADP2441 supports a precharged condition. If the output voltage is
    precharged prior to enabling, the control logic prevents inductor current
    reversal by holding the power MOSFETs off until…
  • ADP2441 Peak Current Limit

    The ADP2441 has a peak current limit of 1.6A.  Does this mean I can operate
    the ADP2441 at 1.6A Load current?

     

    No, peak inductor current does not mean the average load current.  The average
    inductor current is equal to the output (load…

  • ADP2441 VCC Pin

    What is VCC pin in the ADP2441?

     

    VCC pin is the output of the internal low dropout regulator. Internal regulator
    supplies power for the internal controller and driver circuitry.  A 1 µF
    ceramic capacitor between VCC and AGND and a 1 µF…

    The ADP2441 has internal FETS that are optimized for high efficiency. ADP2441
    offers peak
    efficiency up to 94%.

    To further improve the efficiency…
  • RE: Using of 2 ganged FBs ADD5211

    Hi Jon,

    Great!

    I will recommend ADP2441 and ADP8140 with your ADisimPE files and, 2 PPT documents to our customer.

    Anyway customer is proceeding to make his 2type PWBs with your ADD5211.

    When he needs buck type driver then I can recommend ADP2441…

  • ADP2441 - VCC goes low when VIN > 8.5V Latch Up

    Hi,

    I have two ADP2441 regulators on the PCB one at 3.3V (which is working as expected) and one at 5.8V (Schematic included).

    When the second regulator is unloaded it behaves normally (reaching regulation at approx VIN= 7V) until VIN > approx 8.5V at…
