High-voltage circuits by 7555

Power Supply circuits | By: Diagram mania

This is a pulse-mode transformer circuit that I have some experience with. I used this successfully in combination with a Polaroid transducer. Introduction The circuit can be used to generate a voltage of about 70V using a current of about 4 mA @ 6V input voltage. The use of an easily available stroboscope trigger coil […]

DC to DC converter step up 4.5V-12V to +15V 0.5A With MAX1846

Power Supply circuits | By: Diagram mania

This is next Good IC DC to DC converter From web http://www.maxim-ic.com. Read intro Detail Please: The MAX1846 Circuit The MAX1846 inverting circuit to implement a switch-mode power supply that provides a -15V at 0.5A output from a 4.5V to 12V input. This MAX1846 circuit also adds a few components to the minimum circuit implementation. […]

DC5V to DC30V Converter By 74HC14

Power Supply circuits | By: Diagram mania

Here is a power supply which makes about +30V from +5V power supply. The direct current is changed into the alternating current by the oscillator which used the schmitt trigger inverter which has the hysteresis characteristic and the resonance circuit. The high DC voltage (+50V) is made with the alternating voltage using the voltage amplification […]

2W Switching Power Supply with 2N3053

Power Supply circuits | By: Diagram mania

In this small switching power supply, a Schmitt trigger oscillator is used to drive a switching transistor that supplies current to a small inductor. Energy is stored in the inductor while the transistor is on, and released into the load circuit when the transistor switches off. The output voltage is dependent on the load resistance […]
