Design Features Powering highly capacitive loadsCapacitance at the input of the DC-DC converter plays a vital role in keeping the converter stable. Large amounts of capacitance at the output of the DC-DC converter can provide significant challenges in the power system. Digital power control for high-current DC-DC design The drawback of digital power is latency–the time between acquisition of feedback signal and generation of subsequent modulated output–which has resulted in slower transient response than equivalent analogue controllers. more online... | Design Ideas One wire delivers power, data to LCD moduleEmbedded systems typically use HD44780-type LCD displays as it is considered the most popular alphanumeric display controller. The interface comprises at least 14 pins: 8 for data, three for control, two for power supply, and one for contrast. IF output signal switch reduces noise in shortwave receivers This is a description of a noise suppression strategy, not about a specific design. I've done this thing twice, once on an old Hallicrafters S-20R short-wave receiver and again sometime later, on an R-390A receiver. more online... |
