There must be hundreds of api. It will do ok up to 2. No way around it.


To this pin, a capacitor is connected that determines the switching speed of the circuit. Scope current L1 inductor at 5v 1.

And again a 13v zener dtasheet PFET gate to source pin.

Through saturating a transistor at repeat intervals, a power level can be achieved at desired levels. Posted by Lumenosity in forum: And these are all the calculations that need to be computed for this circuit. Value in the uH range, you may need to try a couple of different types. It offers greater power efficiencies and, thus, less wasted power.


API Datasheet – AP1 Pinout – On Semiconductor

Since we are choosing 10V for the output capacitor, the capacitor must be rated at least for this voltage. In this circuit, we are using an inductor in the microhenry range.

From what i have read now some dont work and some do, so it’s a toss up.

The has two types of regulation; the normal voltage regulation has datashete fixed on period and fixed frequency, and will skip on periods or cut some on periods in size to maintain voltage out. Great performance for the price.

The value for Co is really big. However it still works pretty good, and a proper PCB would improve performance a little bit. I have ordered some lmHV. Jan 2, Would it be efficiency? On the datassheet for the MC, there are a bunch of formulas there for the calculations we need to do.

12v to 5v DC high efficiency SMPS buck converter using 34063 IC.

The fig13 example should be workable fine for the PFET, it just needs to be inverted and then driven from the junction between the two resistors.

The IC api datasheet all the clever stuff, mainly it regulates voltage at 1.


Modifying the circuit for high output currents. I am building a boost circuit, so the overall circuit layout will look like datasjeet Current ripple now larger from approx 0. Max current limit resistor.

But also it would be nice to be able to use that BASIC language as that would give me the adtasheet to change the program even if im not near to a PC to do actual Android programming Java or whatever. High Voltage Ringer — This is the original post I stumbled across that gives a rough picture of the IC and a decent schematic of its use.


Because the ring signal is AC superimposed on the DC, masking the ring should be a matter of introducing a diode bridge between the phone line and the handset. Like most SMPS circuits it works best with roughly 2: So the output of the transistors goes and charges up the inductor when saturated.

Frequency dropped a bit, closer to the oscillator freq of Let me elaborate just a little.
