ISL6740IVZ

DC DC Switching Controllers Overview

The ISL6740IVZ is a flexible, double-ended voltage mode PWM controller manufactured by Intersil. It operates at a switching frequency of 1 MHz with a maximum duty cycle of 83%. The device provides two outputs and supports an output current of 500 mA. Designed for half-bridge, full bridge, and push-pull configurations, it features an adjustable oscillator for precise control. The component functions within a temperature range of -40°C to +105°C and is housed in a TSSOP-16 package.

DC DC Switching Controllers Feature Summary

• Supports half-bridge, full bridge, and push-pull power conversion topologies
• Features an advanced BiCMOS design with low operating current
• Provides flexible oscillator control for frequency, duty cycle, and dead time adjustment

DC DC Switching Controllers Applications

• Half-bridge power converter designs
• Full bridge power supply architectures
• Push-pull DC-DC conversion systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'VZ' corresponds to the TSSOP-16 tube packaging variant rather than tape-and-reel options. Confirm RoHS compliance status through official documentation as indicated in datasheets. Ensure the source document explicitly lists this part number to avoid confusion with similar family members like the ISL6741 or ISL6740IBZ-T variants which may have different pinouts or electrical characteristics.

DC DC Switching Controllers Selection Notes

Select this component when a voltage mode control architecture is required for double-ended converter topologies. It is suitable for applications needing adjustable frequency up to 1 MHz and precise dead-time management. Consider the TSSOP-16 package constraints and the specified operating temperature range. Compare against the ISL6741 if current mode control is preferred instead of voltage mode for the same application requirements.

DC DC Switching Controllers Part Context

This part belongs to the ISL6740/ISL6741 family of low-power PWM controllers from Intersil (now Renesas). The family distinguishes between voltage mode (ISL6740) and current mode (ISL6741) operation while sharing similar flexibility in oscillator settings. These controllers are designed for efficient power conversion across various industrial and commercial power supply applications.

DC DC Switching Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct replacements such as other ISL6740 variants only if datasheet parameters match exactly.
