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. Available in a 5 x 6mm QFN ...

The PLD (programmable-logic-device) code in Listing 1 creates ... and loads AVALUE into the holding register. When ENABLE=0, the PWM output becomes 0 (off); when ENABLE=1, the PWM generator produces ...

Adding rail-to-rail comparator U3 to the sawtooth from U2 produces a voltage-controlled PWM generator whose voltage input is the non-inverting input of U3 and whose output is the output of U3. If a ...
