Intersil ISL6226
The ISL6226 provides power control and protection for two user selected output voltages required in high-performance notebook PC applications. The IC integrates a fixed, selectable frequency pulse-width-modulation (PWM) controller and a 3A LDO linear regulator controller with monitoring and protection circuitry in a single 24 lead SSOP package. The PWM controller regulates the battery input voltage to a user selected output voltage.| Part No. | ISL6226 |

APPLICATIONS
Synchronous converter and hysteretic operation at light loads contribute to a high efficiency over a wide range of input voltage and load variation. Efficiency can be further enhanced by using the lower MOSFET’s rDS(ON) as the current sense element. Input voltage feed-forward ramp modulation, current-mode control, and internal feed-back compensation provide fast and stable handling of input voltage load transients encountered in advanced portable computer chip sets. The internal linear regulator controller provides a user selected high current output from an unregulated input with user selected current limit.FEATURES
