ISL6741IVZ

DC DC Switching Controllers Overview

The ISL6741IVZ is a current mode PWM controller in the ISL6740/ISL6741 family, designed for half-bridge, full-bridge, and push-pull topologies. It features an adjustable switching frequency up to 1 MHz, a maximum duty cycle of 83%, and dual outputs with 500 mA drive capability. Operating within a supply voltage range of 9 V to 16 V, it supports clock synchronization and includes soft-start functionality. The device operates between -40°C and +105°C and is housed in a 16-lead TSSOP package.

DC DC Switching Controllers Feature Summary

• Advanced BiCMOS design providing low operating current and precise control over frequency, duty cycle, and dead time.
• Bidirectional synchronization signal allows oscillator locking to external clocks or paralleled units for noise-sensitive applications.
• Integrated protection mechanisms including internal over-temperature protection and fault annunciation capabilities.

DC DC Switching Controllers Applications

• Half-bridge power conversion circuits
• Full-bridge power conversion circuits
• Push-pull power conversion circuits

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized channels as the manufacturer may have updated labeling or packaging standards. Confirm RoHS compliance status and specific suffix variations against official datasheets prior to integration. Ensure storage conditions meet moisture sensitivity level requirements to maintain device reliability during assembly processes.

DC DC Switching Controllers Selection Notes

Select this model for applications requiring current-mode control in isolated DC-DC converters. Compare against the voltage-mode ISL6740 variant if different control characteristics are needed. Verify that the 16-TSSOP package dimensions fit the target PCB layout constraints and thermal management requirements for the intended operating environment.

DC DC Switching Controllers Part Context

Part of the ISL6740/ISL6741 flexible double-ended PWM controller family from Renesas Electronics Corporation (formerly Intersil). This series targets efficient power conversion solutions with adjustable parameters for various industrial and commercial power supply designs.

DC DC Switching Controllers Replacement Considerations

Check for ISL6741IBZ (SOIC package) or ISL6741IV-T (tape and reel) for equivalent electrical performance with different packaging formats. Verify pin compatibility and thermal characteristics when substituting packages.
