AP3586AMPTR-G1

Overview

The AP3586AMPTR-G1 is a single-phase synchronous buck PWM controller manufactured by Diodes Incorporated. It operates with a fixed switching frequency of 300 kHz and supports an input voltage range up to 13.2V, powered by a 4.5V supply. The device features an internal 0.6V reference and allows for an output voltage range from 0.6V to 80% of the VIN. It utilizes voltage-mode control with a duty cycle capability of 0 to 80%, designed for applications requiring fast transient response and simple single-loop regulation.

Feature Summary

• Supports both tracking mode and stand-alone operation modes
• Integrates an internal 0.6V reference for precise regulation
• Features simple single-loop voltage-mode PWM control architecture

Applications

• Single-phase synchronous buck power conversion systems
• Voltage regulation modules requiring fast transient response
• Applications supporting tracking mode synchronization

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix matches the required package and tape-reel specifications. Check for End-of-Life status or Product Change Notices regarding fabrication sites. Ensure compliance with RoHS3 standards and verify moisture sensitivity levels prior to assembly.

Selection Notes

Select this controller for designs requiring a 300 kHz fixed frequency synchronous buck topology. It is suitable for inputs up to 13.2V with outputs adjustable down to 0.6V. Consider the 80% maximum duty cycle limitation when designing for high step-down ratios. Verify that the application environment supports the specified operating temperature range and thermal requirements.

Part Context

This component belongs to the AP3586 series of switching controllers within Diodes Incorporated's PMIC portfolio. It is categorized under DC-DC switching controllers with a buck topology. The part is distinct from operational amplifiers or logic gates sharing similar numerical prefixes in other manufacturers' lineups.

Replacement Considerations

Consult official Product Change Notices for qualified alternative fabrication or assembly sites. Verify pinout and electrical parameter compatibility before substituting with other buck controllers. No direct public substitute part numbers are confirmed in the provided documentation.
