ISL6741IBZ-T

DC DC Switching Controllers Overview

The ISL6741IBZ-T is a current mode PWM controller in the ISL6740/ISL6741 family, designed for half-bridge, full bridge, and push-pull topologies. It features a flexible oscillator with adjustable switching frequency up to 1 MHz (2 MHz max per datasheet), maximum duty cycle of 83%, and output drive current of 500 mA. The device operates within a temperature range of -40°C to +105°C and utilizes a 16-SOIC package. Key electrical parameters include a supply voltage range of 9V to 16V and low start-up current of 95µA.

DC DC Switching Controllers Feature Summary

• Supports half-bridge, full bridge, and push-pull power conversion configurations
• Features bidirectional synchronization for clock locking or paralleling units
• Includes internal over-temperature protection and fault annunciation capabilities
• Provides adjustable soft-start and input undervoltage lockout functions

DC DC Switching Controllers Applications

• Half-bridge DC-DC converters
• Full-bridge isolated power supplies
• Push-pull converter architectures

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential counterfeits. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Check for end-of-life notifications as some variants may be discontinued. Ensure proper ESD protection protocols are followed during handling and installation processes.

DC DC Switching Controllers Selection Notes

Select this part for applications requiring current-mode control with precise duty cycle and dead-time adjustment. Suitable for noise-sensitive designs utilizing the bidirectional SYNC feature. Consider thermal management needs given the operating temperature range. Compare against ISL6740 if voltage-mode control is preferred instead of current-mode operation for specific topology requirements.

DC DC Switching Controllers Part Context

Part of the ISL6740/ISL6741 family from Intersil (Renesas), offering flexible double-ended PWM controllers. The ISL6741 variant specifically implements current-mode control, distinguishing it from the voltage-mode ISL6740. Designed for low-power, adjustable-frequency applications using advanced BiCMOS technology to achieve low operating currents and high performance in compact packages.

DC DC Switching Controllers Replacement Considerations

ISL6741IBZ is the non-tape version of the same functional device. ISL6741IVZ offers identical functionality but in a TSSOP-16 package instead of SOIC-16. Verify pin compatibility and thermal characteristics when substituting between package types.
