AZ494CM-E1

Overview

The AZ494CM-E1 is a pulse-width modulation (PWM) control circuit manufactured by Diodes Incorporated. It operates as a voltage-mode switching controller designed for power management applications. The device supports an input voltage range from 7 V to 36 V, with a nominal operating voltage of 15 V. It features a maximum output current capability of 0.25 A. The component is housed in a 16-pin Small Outline Package (SOP/SOIC). It is rated for operation within a temperature range of -40 °C to 85 °C and complies with RoHS standards.

Feature Summary

Implements voltage-mode pulse-width modulation control technology for switching regulation.
Provides robust input voltage tolerance suitable for standard 15 V systems.
Delivers high drive current capability for direct gate driving applications.

Applications

DC-DC converter designs requiring PWM control
Power supply units utilizing voltage-mode regulation
Industrial power management integrated circuits

Procurement Notes

Verify the specific package variant and suffix codes against official Diodes Incorporated documentation before procurement. Confirm that the AZ494CM-E1 designation aligns with the required 16-pin SOP form factor and industrial temperature specifications. Ensure compliance with current environmental directives such as RoHS requirements as stated in the manufacturer's datasheet.

Selection Notes

Select this component when a dedicated voltage-mode PWM controller is required for power conversion stages. Consider the 0.25 A output drive strength and the 7 V to 36 V input range for compatibility with system power rails. Evaluate the 16-pin SOP package constraints for PCB layout and thermal management relative to alternative controllers in the AZ494 series.

Part Context

The AZ494CM-E1 belongs to the AZ494 series of switching controllers produced by Diodes Incorporated. This series focuses on providing reliable pulse-width modulation solutions for power management integrated circuits. The component serves as a core control element in various power supply architectures, distinguishing itself through its specific voltage-mode operation and drive capabilities within the PMIC category.

Replacement Considerations

Consult official Diodes Incorporated substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics with other members of the AZ494 family or compatible PWM controllers to ensure functional equivalence without modifying existing circuit designs.
