Switching Regulator with L4972A

The LA9472A is a 2A monolithic step down switching regulator operating in continuous mode and realized in a new BCD technology allowing the integration of isolated, vertical DMOS power transistors with mixed CMOS/bipolar transistors. The device can deliver 2A at an output voltage adjustable from 5.1V to 40V and contains diagnostic and control functions that make it particularly suitable for microprocessor based systems. [...]

Variable voltage 0-25V 10A Switching Regulator by L4970

When friends want Variable power supply Switching Regulator Circuit. I thinks this circuit may like friends certainly. It can Adjustable from 0V to 25V at current 10A. By have the prominent point again be the small-sized. Because of use integrated readymade circuit. Decrease the heat has of plentiful follow circuit picture. It uses , IC – L4970 , by use , VR-10K , fine decorate voltage follow want. The LED for show the circuit. A friend should use transformer 10A sizes and are high class ,volt 28VAC and 8VAC with. The capacitors should durable voltage about 50V. Other hardware a friend pleases to see in the circuit yes.

5V-12V Multiple Supply Switching regulator by L4970 and L4974A

Today take Multiple Supply Switching regulator Circuit. Come to deposit friends keep see in rows think out it can give Voltage supply about 5V 10A and 12V 3.5A. In same circuit by the character of Switching Regulator at use integrated readymade circuit. Work the character Synchronization between IC L4970 and L4974A. When friends see circuit think use a little many equipments. A friend feeds power supply input 35V 10A min just one group can give voltage output follow want. By the L1 use 80 uH sizes and , L2 = 300uH. The detail is other , request friends , see in the circuit please yes.
