The ISL6440 provides the power control and protection for four output voltages required by microprocessors used in high-performance, graphics intensive gateway applications. The IC integrates a voltage-mode PWM controller and three linear controllers, as well as the monitoring and protection functions into a 28-pin SOIC package. The PWM controller regulates the microprocessor core voltage with a synchronous-rectified buck converter. The linear controllers regulate the computer systems AGP 1.5V or 3.3V bus power, the 1.5V GTL bus power, and the 1.8V power for the North/South Bridge core voltage and/or cache memory circuits. The ISL6440 includes an Intel-compatible, TTL 5-input digital-to-analog converter (DAC) that adjusts the core PWM output voltage from 1.3V DC to 2.05VDC in 0.05V steps and from 2.1V DC to 3.5VDC in 0.1V increments. The precision reference and voltage-mode control provide 1% static regulation. The AGP bus power linear controllers output (VOUT2) is user-selectable, through a TTL-compatible signal applied at the SELECT pin, for levels of 1.5V or 3.3V with 3% accuracy. Based on the status of the FIX pin, the other two linear regulators provide either fixed output voltages of 1.5V3% (VOUT3) and 1.8V3% (VOUT4), or user-adjustable by means of an external resistor divider. All linear controllers can employ either N-Channel MOSFETs or bipolar NPNs for the pass transistor.
First, each operational amplifier can operate with rail to rail input and output voltages. This means the signal input voltage and output voltage can be equal to or near to the positive and negative supply voltages. This feature allows numerous analog serial stages and flexibility in input signal bias levels. Secondly, each device was designed to accommodate mixed applications where digital and analog circuits may operate off the same power supply or battery. Thirdly, the output stage can typically drive up to 50pF capacitive and 10KΩ resistive loads.
Control input to the VCO. This voltage determines the output frequency and is derived from filtering the CPOUT voltage. Internal compensation node. This pin must be decoupled to ground with a 10nF capacitor. Internal compensation node. This pin must be decoupled to VVCO with a 10uF capacitor. VCO output. The output level is programmable from -6dBm to -13dBm. See Page 18 for a description of various output stages. VCO complementary output. The output level is programmable from -6dBm to -13dBm. See Page 18 for a description of various output stages. Charge Pump Ground. This is the ground return path for the charge pump. Digital Ground. Analog Ground. This is the ground return path of the prescaler & VCO.
