This DC DC inverter circuit diagram electronic project is based on the MAX724 monolithic, bipolar, pulsewidth modulation, switch-mode DC DC regulator optimized for step-down applications. This MAX724 inverter project is a 5 volts DC inverter circuit that require few external components and supports a wide range input voltage from 4.5 volts up to 35 volts .
The maximum output current provided by this 5 volts DC inverter circuit is 1 A
If a lower output current is needed, then the current rating of both D1 and L1 may be reduced.
This RS232 power supply circuit diagram is an simple RS-232 Line Driver Power Supply, that operates from an input voltage as low as 4.2V, and delivers an output of ±12V at ±40 mA with an efficiency of better than 70%.
This RS232 power supply circuit provides a load regulation of ±1.25% (from 10% to 100% of full load) and a line regulation of ±0.08%. Other notable features include a cycle-by-cycle current limit and an output voltage ripple of less than 40 mVp-p.
A very simple 3 to 12 volt step up dc dc converter circuit diagram electronic project that require few external components can be designed using the LM2700 step up 3 to 12 volt DC DC converter with a 3.6A, 80mohms internal switch and pin selectable operating frequency.
The LM2700 can be operated at switching frequencies of 600kHz and 1.25MHz allowing for easy filtering and low noise.
