V OUT is the voltage that we want output, which is 10V. Energy conversion efficiency is very high due mainly to the choice of external components used with the cheap SMPS IC.

Right now i have constructed quite a while back actually a four channel ‘meter’ that can measure voltages and with some simple interfaces can datasheett current too.

Pin 2 is datadheet emitter of both of the switch and drive transistors. It’s an 8-pin chip. I have not tried this configuration myself and cannot offer any further advice! As you can see the circuit is minimum parts. It explains everything, better than I can. Dec 28, 2. The circuit is meant for 5v out, It determines the switching speed of the circuit.

MCA DC-DC Converter IC Pinout, Equivalent, Circuit & Datasheet

This language allows quick changes right on the Android Tablet so i can set up different things quite easily. So from these formulas, we find the value of all the components we need.

As you can see the circuit is minimum parts.

Then out of the blue it occurred to me to just switch the polarity for the handset. Because of the 6k8: December 13, at The external PFET allows currents up to a few amps at good efficiency, however I have used hard current limiting at 1.

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

So with the parts values I chose it was peaking on the current limit and in sync with the inductor ripple and the internal oscillator. But what it doesnt do is read RS What would be the difference between your circuit and a regulator combination like a and an emitter follower? Oh ok, they also include home made boot strap drivers, which is a nice change. The pin 1 and 2 has a pair of transistors between them which is switching to regulate the required output voltage. You can change this to whatever voltage you want.

To the inverting terminal, we connect a resistor network that allows us to determine the output voltage gain. Pin 7 is the I PK pin. Follow Blog via Email Enter your email address to follow this blog and receive notifications of new posts by email.

What i’d like to do is use the Android Tablet the same way, even if it means creating new software for the Android environment rather than Windows. Through saturating a transistor at repeat intervals, a power level can be achieved at desired levels. The downside is they are a bit noisier than linear regulators.

Inside the MC is a reference regulator that inputs 1. The resistor between Vin and pin7 sets the max inductor current limiting, this was set by me to roughly 0. Pin 5 is the comparator inverting input terminal.

Hi MrRB, Oh yeah pretty nice!

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. To this pin, we connect our positive voltage supply.

Hi Mr AL, thanks. The output voltage is set by forming a potential divider at pin 5.

How we calculated most of the values of the components of each of the parts of the circuits are through the formulas on the data.

It may be hard to find a 0.
