MX045HST50.000MHZ Datasheet Oscillator The internaloscillatoris free running and requires no external components. The maximum duty cycle is 100%. This is another advantage of using a P-channel MOSFET for the high-side drive: it can continuously turned on. A frequency foldback mode is enabled if the voltage on the feedback pin (pin 3) is less than 0.3V. In frequency foldback, the oscillator frequency is reduced by approximately a factor of4. Frequency foldback is used to limit the energy delivered to the output during a short circuit fault condition. Voltage Setting Components The MIC2193 requires two resistors to set the output voltage as shown in Figure 4. MX045HST50.000MHZ Price
MX045HST50.000MHZ on stock As shown in Figure 4 and 5 burst-mode control produces low-frequency waveform comparing to the switching frequency. Part of the power loss in this low frequency becomes audible noise. Therefore, burst-mode control is not suitable for high power applications such as more than 20 W. D ata Mem ory Interface T he data memory address bus (D MA) is 14 bits wide. T he bidirectional external data bus is 24 bits wide, with the upper 16 bits used for data memory data (D MD) transfers. T he data memory select (DMS) signalindicates access to data memory and can be used as a chip select signal. The write (WR) signal indicates a write operation and can be used as a write strobe. T he read (RD) signalindicates a read operation and can be used as a read strobe or output enable signal. |
