When the PWM input transitions to logic-1, one end of C is grounded (via U2b) while the other becomes the now single-ended input to U1c (via U2a). Then things get even less conventional. The ...

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 ...

When the PWM signal goes to logic zero, sample-and-hold capacitor C 1 charges to V IN. When the PWM signal cycles to logic one, op amp A 1 drives the R 1 C 1 positive-feedback loop, creating a ...

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. The LT3954, a DC ...

Linear Technology has unveiled a new pulse width modulation (pwm) generator with 48 independent channels. According to the IC specialist, each channel has an individually adjustable 12bit (4,096 steps ...

When it is finished, I’ll release the PWM generator part as a library (.NET dll) and as source code, so you can port it to other platforms. About the part on spam-, bloat- and spyware on my site: ...

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 ...

Linear Technology announces the LT8500, a pulse width modulation (PWM) generator with 48 independent channels. Linear Technology announces the LT8500, a pulse width modulation ...
