DESCRIPTION
The AIC1529 is a quad high-side power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. Both high-side switches are MOSFET with 110mW RDS(ON), which meets USB voltage drop requirements for maximum transmission wire length.
Multi-purpose open-drain fault flag output indicates over-current limiting, thermal shutdown, or undervoltage lockout for each channel. Output current is typically limited to 1.3A, and the thermal shutdown functions of the power switches independently control their channel under overcurrent condition.
Guaranteed minimum output rise time limits inrush current during hot plug-in as well as minimizing EMI and prevents the voltage at upstream port from dropping excessively.

DESCRIPTION
The AIC1660 is a monolithic CMOS switched capacitor voltage converter. Designed to be an improved direct replacement for the popular 7660 and LTC1044, the main function of the AIC1660 is to convert a positive input voltage in the range of 1.5V to 6V to the corresponding negative output voltage in the range of -1.5V to -6V. The input voltage can also be doubled (VOUT = 2VIN ), divided (VOUT = VIN /2 ), or multiplied (VOUT = ±nVIN), as shown in application examples.
The chip contains a series DC power supply regulator, oscillator, control circuitry and four output power MOS switches. The frequency of oscillator can be lowered by the addition of an external capacitor to the OSC pin, or the oscillator may be over-driven by an external clock.
The boost function is available to raise the oscillator frequency to optimize performance in specific applications. The “LV” terminal may be tied to GND to improve low input voltage (VIN £3V) operation, or be left floating for input voltage larger than 3V to improve power dissipation.
The AIC1660 provides performance superior to previous designs by combining low output impedance, low quiescent current with high efficiency, and by eliminating diode drop voltage losses. The only required external components are two low cost electrolytic capacitors.

FEATURES
*Lowest Output Impedance (Typical 35W at VIN=5V).
*Improved Direct Replacement for 7660.
*1.5V to 6V Operation.
*No External Diode Required.
*Simple Conversion of +5V to -5V.

*Boost Pin for Higher Switching Frequency.
*Improved SCR Latchup Protection.

APPLICATIONS

DESCRIPTION
AIC1532 is a dual input regulator with VAUX drive control capable of delivering 3.3V/500mA continuously. The output power is provided from three independent input voltage sources on a
prioritized basis. Power is always taken in priority using the following order VCC, VSBY, and VAUX.
AIC1532 meets Intel’s “ Instantly Available ” power requirements which follows the “Advanced Configuration and Power Interface“ (ACPI) standards. When either VCC or VSBY is present, the device automatically enables the regulator and produces a stable 3.3V output VOUT. When only VAUX (3.3V) is present, the drive control output will turn-on an external PMOS switch from an auxiliary 3.3V supply VAUX to VOUT.
The IC also prevents excessive current from flowing VOUT to either input voltage or ground when the output voltage is bigger than the input voltage.
All the necessary control circuitry needed to provide a smooth and automatic transition between all the three supplies has been incorporated. This allows both VCC and VSBY to be dynamically switched without loss of output voltage.

FEATURES
*Continuous 3.3V Output from Three Inputs.
*Complete Power Management Solution.
*VCC, VSBY Regulator Supplies 500mA Output.
*Built-in Hysteresis When Selecting Input Supplies.
*Drive Control Signal for External VAUX Switch.
*Output can be Forced Higher than Input (Off-State).

APPLICATIONS
