توضیحات
AP1510 يک ايسي رگولاتور ولتاژ با ريپل خروجي پايين ، بازدهي بالا ميباشد.مدار کنترلر PWM قابليت ايجاد ديوتي سايکل بين 0 تا 100 درصد را دارا ميباشد. همچنين قابليت فعال يا غير فعالسازي با پايين EN ، محافظ اضافه جريان ، محافظ اتصال کوتاه داخلي ميباشد. و هنگام اضافه جريان يا اتصال کوتاه، فرکانس عملياتي ان از 300 کيلوهرتز به 30 کيلوهرتز کاهش مي يابد
Description
AP1510 provides low-ripple power, high efficiency and excellent
transient characteristics. The PWM control circuit is able to vary the
duty ratio linearly from 0 up to 100%. This converter also contains an
error amplifier circuit. An enable function, an over current protection
and a short circuit protection are built inside, when OCP or SCP
happens, the operation frequency will be reduced from 300kHz to
30kHz. Also, an internal compensation block is built in to minimum
external component count.
With the addition of an internal P-channel Power MOS, a coil,
capacitors, and a diode connected externally, these ICs can function
as step-down switching regulators. They serve as ideal power supply
units for portable devices when coupled with the SO-8 package,
providing such outstanding features as low current consumption.
Since this converter can accommodate an input voltage up to 23V, it
is also suitable for the operation via an AC adapter.
