Overview
The ISL6235CA is a power management integrated circuit designed for voltage regulation applications. It functions as a switching controller with current-mode operation and a maximum switching frequency of 345kHz. The device supports surface mount packaging in a 24-SSOP format. It provides thermal stability through internal current limiting and thermal shutdown protection mechanisms that activate when junction temperatures exceed safe limits.
Feature Summary
- Advanced triple PWM only mode and dual linear control architecture
- Current-mode switching controller operation
- Internal current limiting for thermal stability
- Thermal shutdown protection activation
Applications
- Voltage regulation systems
- Step-down power conversion circuits
- Step-up power conversion circuits
Procurement Notes
Verify the specific manufacturer documentation to confirm exact electrical parameters and pin configurations. Ensure compatibility with required operating temperature ranges, typically specified between -10°C and +85°C. Confirm package details match the 24-SSOP or equivalent surface mount requirements. Cross-reference part numbers carefully as suffixes may indicate variations in packaging or testing standards without altering core functionality.
Selection Notes
Select this component for applications requiring efficient step-down or step-up power conversion with precise voltage regulation. The current-mode control offers stable performance under varying load conditions. Consider the thermal management capabilities provided by internal protection features. Ensure the design accommodates the specified switching frequency range for optimal efficiency and electromagnetic interference compliance.
