Microprocessor Voltage Regulators (1 Phase)
AC/DC Micro Processing Control Voltage Regulator ; are RISC Microprocessing semi conductor type smart instruments. That's why they can be used with 100% safety in sensible electronical apparels. AC/DC Microprocessing controlling Voltage Regulators are functionning based on true RMS Effective measurement value. Thus the network input voltage is not affected by sudden changes in network voltage or wave shape failure hence they might work easily with output voltage fast correction ( 220 VAC , ± 1 ).

The AIC1579 is a high-power, high-efficiency voltage-mode DC/DC controller for motherboard VI/O power supply applications. Designed to drive an N-channel MOSFET in a standard buck topology, the AIC1579 features a high voltage CMOS output driver, short-circuit protection, and 8-pin package.
An external 4-bit Digital-to-Analog Converter (DAC) can be used along with the AIC1579 to adjust the output voltage from 2.0V to 3.5V in 0.1V increments. Table 1 on the following page specifies the corresponding output voltage for 16 combinations of DAC inputs as in the typical application circuit.
The 200KHz switching frequency allows for using small external components while maintaining high conversion efficiency. The 11MHz bandwidth and 6V/uS slew rate of the error amplifier ensures high converter bandwidth and fast transient response.
The AIC1579 provides adjustable overcurrent and short-circuit protections by sensing the output current across the on resistance of the external N-channel MOSFET rather than an external low value sense resistor.
The AIC1579L provides lower reference voltage (1.30V) than the default (2.00V, AIC1579) for lower VOUT requirement.

The AIC1638 is a high efficiency step-up DC/DC converter for applications using 1 to 4 NiMH battery cells. Only three external components are required to deliver a fixed output voltage of 2.7V, 3.0V, 3.3V, 4.5V or 5V. The AIC1638 starts up from less than 0.9V input with 1mA load. Pulse Frequency Modulation scheme brings optimized performance for applications with light output loading and low input voltages. The output ripple and noise are lower compared with the circuits operating in PSM mode.
The PFM control circuit operating in 100KHz (max.) switching rate results in smaller passive components. The space saving SOT-23, SOT-89 and TO-92 packages make the AIC1638 an ideal choice of DC/DC converter for space conscious applications, like pagers, electronic cameras, and wireless microphones.
