The PI Expert software design tool gives you everything you need for a first-cut design, giving you a preliminary schematic and transformer design. As I mentioned before, the most sane approach for this requirement appears to be a basic 2-output (5V and 24V) supply with a small linear reg...

Component selection and schematic design is only half of the supply design process. Proper PCB layout of a switching supply design is always critical. In fact, its importance can not be overstated. Good layout design optimizes supply efficiency, alleviates thermal stress, and most importantly, mini...

Like all other LTC PowerPath controllers, the LTC4089/LTC4089-5 can be configured to accept 5V adaptor/USB input in the same USB connector or different connectors with different current limits by changing the resistance connected to CLPROG pin. Figure 8 shows the schematic d...
PERSONAL COMPUTER POWER SUPPLY Using two mutually synchronized devices it is pos- sible to obtain a four output power supply suitable for power a microprocessor system. V01 = 5.1V/4A V02 = 12V/2.5A (up to 4A) V03 = –5V/0.2A V04 = –12V/0.2A The schematic diagram is shown in ...
Instead, i would use a transistor to control the power of the 555, exactly as i have done in this circuit: http://pcbheaven.com/circuitpages/Two_Speed_Temperature_Fan_Controller/ T1 controls the power of the 555. As a matter of fact, you can use a part of this schematic (T1-555-...
