DC DC Switching Controllers datasheet and documents for ISL6522IBZ-T
DC DC Switching Controllers Overview
The ISL6522IBZ-T is a synchronous rectifier PWM controller designed for high-performance microprocessor power applications. It operates in a buck topology with a fixed 200kHz switching frequency and supports output voltages from 800mV to 12V. The device provides up to 500mA of drive current and functions within a supply voltage range of 10.8V to 13.2V. It utilizes a 14-SOIC package and is rated for an operating temperature range of -40°C to +85°C.
DC DC Switching Controllers Feature Summary
- Integrates complete control and protection for DC-DC converters optimized for microprocessor loads
- Drives two N-channel MOSFETs in a synchronous rectified buck topology
- Employs rDS(ON) sensing of the upper MOSFET to eliminate external current sense resistors
- Features a 15MHz gain-bandwidth error amplifier for fast transient response
DC DC Switching Controllers Applications
- Power supplies for Pentium, Pentium Pro, PowerPC, and Alpha PC microprocessors
- High-power 5V to 3xV DC-DC regulators
- Low-voltage distributed power supplies
DC DC Switching Controllers Procurement Notes
Verify component authenticity through authorized Renesas channels due to discontinuation status. Confirm RoHS compliance and moisture sensitivity levels prior to assembly. Review Product Change Notices for any recent manufacturing site updates or label modifications that may affect integration.
DC DC Switching Controllers Selection Notes
Select this part for single-output synchronous buck designs requiring precise voltage regulation. Ensure the application demands a fixed 200kHz frequency and fits within the specified thermal envelope. Validate that the load profile aligns with the integrated driver capabilities and protection thresholds.
