QMV113AD Datasheet Bypass capacitance, and its close mounting to the driver serves two purposes. Not only does it allow optimum performance from the driver, it minimizes the amount of lead length radiating at high frequencyduring switching, (due to the largel) thus minimizing the amount of EMllateravailable for system disruption and subsequent cleanup. It should also be noted that the actual frequency of the EMI produced by a driver is not the clock frequency at which it is driven, but is related to the highest rate of change of current produced during switching, a frequency generally one or two orders of magnitude higher, and thus more difficult to filter if you let it permeate yoursystem. Good bypassingpractice is essential to proper operation of high speed driver ICs. QMV113AD Price Linear regulators require input and output capacitors in order to maintain over-allloop stability. The recommended minimum value for the input capacitor is 0.1 yF. The output capacitor is the dominant pole that provides the high-frequency compensa- tion required for over-all regulator loop stability. These devices are stable with as little as l hcF. However, to ensure stable operation under all conditions and capacitor types, the recom- mended mimmum value is 4.7 yF. The output capacitor may be partially distributed through the load circuits. However, at least 1 hcF should be connected at the regulator using the shortest and widest foil pattern possible. Programming is accomplished by applying the proper voltage (or float condition) on the four digital VID inputs. VID3 is the most significant bit (MSB), and VIDO is the least significant bit (LSB). When all four inputs are low, or grounded, the regulator output voltage is set t0 2V. Each increasing binary count is equivalent to a decrease of 50mv in the output voltage. Therefore, to obtain a l.3V output, the three MSBs are left floating, or high,while only the LSB, VIDO, is grounded. A list of programmed inputs and their corresponding output voltages is shown in Table l. |
