Simple 3 volt to 9 volt with LMC555 Circuit Diagram
in: Converters
Build a 3 volt to 9 volt with LMC555 Circuit Diagram. This is a Build a 3
volt to 9 volt with LMC555 Circuit Diagram. This dc converter is built
with the CMOS version of 555 timer. You can
get 12V too if you change the zener diode to a 12V version.

1.5V Battery to 5V Voltage Converter Circuit Diagram
in: Battery Charger Converters
This is a Simple 1.5V Battery to 5V Voltage Converter Circuit Diagram. Stable and secure 5V DC (at 200mA max) from an
ordinary 1.5V AA sized cell. At the heart of this circuit is IC1 MAX756
from Maxim, which is a CMOS step-up DC-DC switching regulator for small,
low input voltage or battery-powered systems.
Simple 1.5V Battery to 5V Voltage Converter Circuit Diagram
MAX756 accepts a positive input voltage down to 0.7V and converts it
to a higher pin selectable output voltage of 5V (or 3.3V). Typical
full-load efficiency for the this IC is greater than 87%. Max756
combine a switch-mode regulator with an N-channel MOSFET, precision
voltage reference, and power-fail detector in a single monolithic
device. The MOSFET is a “sense-FET” type for best efficiency, and has a
very low gate threshold voltage to ensure start-up under low-battery
voltage conditions (1.1V typ).
The
circuit can be easily wired on a very small rectangular common PCB.All
connections should be kept as short as possible. If available,try to
add a good quality 8 pin DIP socket for IC1. Note that the power
inductor’s (L1) DC resistance significantly affects efficiency. For
highest efficiency, limit L1’s DC resistance to 0.03 Ohm or less. A
thru-hole type standard power inductor can be used. Similarly, the ESR
of all capacitors (bypass and filter) affects circuit efficiency. Best
performance is obtained by using specialized low-ESR capacitors.
50W DC/DC Converters TRACOPOWER with the Highest Power Density
in: Converters
TRACOPOWER launches the high performance TEN50 Series with 12 models
providing 50W power in a 1”x 2”x 0.4 “ compact package. Today already
almost all of applications require a high efficiency of a voltage
conversion. When we add to this requirement also saving of space and a
galvanic isolation, we´ll get to widely used components – DC/DC modules.
The TEN 50 Series models feature a very high efficiency of up to 92%.
Excellent efficiency is maintained in over a wide load range and no
minimum load is required for an accurate output regulation. They are
available in three basic groups – TEN 50-12xx, TEN 50-24xx a TEN 50-48xx
with a wide input voltage range (2:1).
Low thermal losses and the use of highest grade components allow an
operating temperature range of –40°C to +85°C while up to 55°C no forced
air cooling is required. With an optional heat-sink this temperature
can even be increased. An operation without a forced air cooling is
possible even at higher temperatures – at an adequate power derating (
2%/K above 55°C and 2,5%/K above 65°C). The TEN 50 Series comes with
remote On/Off function and have an adjustable output voltage (± 10%).
Protection against overload and short-circuit, very compact dimensions
and a 1500VDC isolation enable usage of TEN 50 modules in virtually any
power application. [Link]
