The ISL6269A is a high-performance notebook PWM controller featuring Intersil's Robust Ripple Regulator (R3) technology that delivers truly superior dynamic response to input voltage and output load transients
The ISL6269A PWM controller features Intersil's Robust‑Ripple‑Regulator (R®) technology, providing fast transient response and +1% regulation accuracy over a wide temperature range. Integrated MOSFET drivers and a bootstrap diode reduce component count and enable a compact implementation.
The device supports programmable PWM frequency (200 kHz‑6 MHz), diode‑emulation mode for light‑load efficiency, and includes comprehensive protection features such as undervoltage, overvoltage, over‑current and over‑temperature detection with fault identification via the PGOOD pin.
| Input voltage range | +5.0 V to +25.0 V |
|---|---|
| Output voltage range | +0.6 V to +3.3 V |
| Output load range | 0 A to 25 A |
| PWM frequency (programmable) | 200 kHz to 6 MHz |
| Regulation accuracy | +1 % from -10 °C to +100 °C |
| Soft‑start time | 1.5 ms |
The controller operates from +5.0 V up to +25.0 V.
It provides undervoltage, overvoltage, over‑current, over‑temperature protection and fault identification via the PGOOD pin.
The digital soft‑start ramps the output in about 1.5 ms.
Integrated MOSFET drivers and a bootstrap diode reduce component count and enable rapid response to voltage and load changes.
