The LT3954, a DC/DC converter designed to operate as a constant-current source and constant-voltage regulator with an internal 5A switch, is now available from Linear Technology.

Linear Technology has announced the LT3954, a dc/dc converter designed to operate as a constant current source and constant voltage regulator with an internal 5A switch.

Supplying a constant current to a variable, low-resistance load, such as a thermoelectric cooler, can be a very inefficient endeavor when using the linear approach. Even powering the linear ...

Grounded base PNP transistor T1 here works as a constant current generator. With 22 ohm resistor for R1, the charging current available at the output of the charger is near 50 mA.

The sink-current generator comprising IC2A and Q3 loads the battery under test, and the resistor-divider network sets the comparator voltages. You can add an optional self-testing button for checking ...
