DC DC Switching Controllers datasheet and documents for ISL6439CB
DC DC Switching Controllers Overview
The ISL6439CB is a single-output PWM switching controller manufactured by Intersil. It operates at a fixed switching frequency of 650 kHz and supports an output voltage range from 0.8 V to 3.3 V with a maximum output current capability of 2000 mA. The device features a maximum duty cycle of 100% and includes an integrated charge pump. It is housed in a 14-lead SOIC package, designed for operation within a temperature range of -40°C to +85°C.
DC DC Switching Controllers Feature Summary
- Integrates a high-performance error amplifier with a 15 MHz gain-bandwidth product and 6 V/μs slew rate for fast transient response.
DC DC Switching Controllers Applications
- Single-phase synchronous rectified buck converters
- Core voltage regulation for processors
DC DC Switching Controllers Procurement Notes
Verify the specific suffix 'CB' against the manufacturer's official documentation to confirm the exact package type and temperature rating. Ensure compatibility with system thermal requirements and input voltage specifications before procurement.
DC DC Switching Controllers Selection Notes
Select this component for applications requiring a single-channel buck controller with high bandwidth error amplification. Confirm that the 14-SOIC package fits the board layout constraints and that the 650 kHz frequency aligns with EMI and efficiency targets.
DC DC Switching Controllers Part Context
This part belongs to the ISL6439 family of switching controllers. While the ISL6439AIRZ variant utilizes a QFN EP package, the ISL6439CB specifically uses a 14-SOIC form factor. Both share core control functionalities but differ in physical footprint and mounting style.
DC DC Switching Controllers Replacement Considerations
The ISL6439CB-T is a tape-and-reel version of the same controller. Verify if reel packaging is required instead of tube packaging for automated assembly processes.
