Description

The AS2843D-8 is an electronic component integrated circuit belonging to the IC chip product category.

The control ICs of the AS3842 family are pin-compatible replacement devices of the UC3842 series of devices commonly used in the industry. These devices are redesigned to offer greatly improved tolerances in power supply manufacturing. The 2.5 V reference has been trimmed to 1.0% tolerance, and the oscillator discharge current is trimmed to provide assured duty cycle clamping rather than specified discharge current. The circuit is more comprehensively specified to ensure all power supply manufacturing tolerance-impacting parameters are guaranteed.

Specifications and features

• Product model: AS2843D-8
• Product category: IC Chips
• Potential uses: Replacement of UC3842 series of devices
• Manufacturer: Astec
• Tolerance: 1.0% for 2.5 V reference

Application Scenarios

The AS2843D-8 is designed specifically for use in situations where improved tolerances in power supply manufacturing are required. It can be used as a replacement device for the UC3842 series of devices, especially in high voltage and high current applications such as power supplies and inverters for various electronic and electrical systems.

Comparison

• Offers greatly improved power supply manufacturing tolerances
• Pin-for-pin replacement devices for UC3842 series of devices
• More comprehensive circuit specification to ensure guaranteed parameters impacting power supply manufacturing tolerances

• May not provide significant benefits for applications that do not require improved power supply manufacturing tolerances
• May not be cost-effective for low voltage and low current applications
• Not suitable for use in applications not involving power supply manufacturing
