High-Performance Notebook PWM Controller with Bias Regulator and Audio-Frequency Clamp
The ISL6269 IC is a Single-Phase Synchronous-Buck PWM controller featuring Intersil"s Robust Ripple Regulator (R3) technology that delivers truly superior dynamic response to input voltage and output load transients. Integrated MOSFET drivers, 5V LDO, and bootstrap diode result in fewer components and smaller implementation area.
Features
• High performance synthetic ripple regulation
• Extremely fast transient response
• External type-two loop compensation
• ±1% regulation accuracy: -10°C to +100°C
• Starts into a pre-biased output
• Wide input voltage range: +7.0V to +25.0V
• Wide output voltage range: +0.6V to +3.3V
• Wide output load range: 0A to 25A
• Programmable PWM frequency: 200kHz to 600kHz
• Power good monitor
• Fault identification by PGOOD pull-down resistance
• Integrated MOSFET drivers with shoot-through protection
• Internal digital soft-start
• Internal 5V LDO for self-biasing from up to 25V
• Configure forced continuous conduction or diode emulation for increased light load efficiency
