ISL97645AIRZ

Power Management - Specialized Overview

The ISL97645AIRZ is a dedicated PMIC for LCD monitors and notebook displays, housed in a 24-QFN (4x4) package. It operates on a 2.7V to 5.5V supply with 1mA typical supply current. The device integrates a boost converter delivering up to 20V AVDD at 2.6A, an integrated VON slice, and a VCOM amplifier featuring 30MHz bandwidth, 50V/μs slew rate, and 400mA peak output current. Switching frequencies are selectable at 600kHz or 1.2MHz. It includes UV and OT protection and functions within a -40°C to 85°C temperature range.

Power Management - Specialized Feature Summary

• Integrates a high-current boost converter capable of generating up to 20V AVDD from low input voltages
• Includes a high-performance VCOM amplifier with significant bandwidth and peak output current capabilities
• Features an integrated VON slice circuitry for precise voltage control
• Provides comprehensive protection mechanisms including under-voltage lockout and over-temperature shutdown

Power Management - Specialized Applications

• LCD Monitors (15 inches and larger)
• Notebook Displays (up to 16 inches)

Power Management - Specialized Procurement Notes

Verify component authenticity through authorized channels due to the discontinued status indicated by recent PCNs. Confirm that the specific suffix 'AIRZ' matches the required RoHS compliance and lead-free specifications. Check for any design-in restrictions or obsolescence notices from Renesas Electronics Corporation before finalizing procurement plans.

Power Management - Specialized Selection Notes

Select this component for applications requiring a compact solution for LCD panel power management. Ensure the system input voltage falls within the 2.7V to 5.5V range. Verify that the thermal requirements align with the -40°C to 85°C operating range. Consider the 24-QFN package size constraints during PCB layout design.
