ISL6440A
Key Features
- Provides four regulated voltages - Microprocessor core, AGP bus, memory, and GTL bus power
- Drives N-Channel MOSFETs
- Linear regulator drives compatible with both MOSFET and bipolar series pass transistors
- Fixed or externally resistor-adjustable linear outputs
- Simple single-loop control design - Voltage-mode PWM control
- Fast PWM converter transient response - High-bandwidth error amplifier - Full 0-100% duty ratio
- Excellent output voltage regulation - Core PWM output: ±1% over temperature - Other outputs: ±3% over temperature
- TTL-compatible 5-bit DAC core output voltage selection - Shutdown feature removed when all inputs high - Wide range 1.3VDC to 3.5VDC
- Power-good output voltage monitor
- Overvoltage and overcurrent fault monitors - Switching regulator does not require extra current Sensing element, uses upper MOSFET’s rDS(ON)
