DC DC Switching Controllers datasheet and documents for ISL6741IB-T
DC DC Switching Controllers Overview
The ISL6741IB-T is a current mode PWM controller from the ISL6740/ISL6741 family, designed for half-bridge, full-bridge, and push-pull power conversion applications. It features an adjustable switching frequency up to 1 MHz, with a maximum duty cycle of 83% and two outputs. The device operates within a temperature range of -40°C to +105°C and provides 500 mA output current capability. Packaged in a 16-lead SOIC or TSSOP, it includes internal over-temperature protection, adjustable soft-start, and bidirectional synchronization.
DC DC Switching Controllers Feature Summary
- Current mode control architecture for precise regulation
- Adjustable oscillator frequency and dead-time control
- Bidirectional synchronization for parallel operation
- Integrated thermal protection and soft-start functionality
DC DC Switching Controllers Applications
- Half-bridge power converters
- Full-bridge power converters
- Push-pull power converters
DC DC Switching Controllers Procurement Notes
Verify component authenticity due to discontinued status. Check RoHS compliance as some listings indicate non-compliance. Confirm package variant (SOIC vs TSSOP) matches design requirements. Validate supplier authorization given limited availability. Review datasheet revisions for any functional updates.
DC DC Switching Controllers Selection Notes
Select this controller for low-power double-ended topologies requiring flexible frequency adjustment. Ensure input voltage ranges match application needs. Consider external components for setting oscillation frequency and soft-start timing. Verify thermal management strategies align with the integrated protection limits.
DC DC Switching Controllers Part Context
Part of the ISL6740/ISL6741 family of flexible double-ended PWM controllers. Manufactured by Intersil, now part of Renesas Electronics. Designed for high-efficiency power supplies using advanced BiCMOS technology. Offers low operating current and precise duty cycle control for noise-sensitive applications.
DC DC Switching Controllers Replacement Considerations
Check for direct pin-compatible alternatives within the ISL674x series. Verify electrical parameters such as switching frequency and output drive strength. Review package dimensions for mechanical compatibility. Consult manufacturer documentation for recommended upgrades or obsolescence notices.
