AP3595FNTR-G1

Overview

The AP3595FNTR-G1 is a dual-phase synchronous rectified buck switching controller manufactured by Diodes Incorporated. It operates within a supply voltage range of 10.8V to 13.2V and supports a switching frequency between 50kHz and 1MHz. The device features two output channels with positive output configuration, housed in a U-QFN4040-24 package with a bare pad. Key control characteristics include enable, frequency control, phase control, and soft start capabilities. The maximum duty cycle is specified at 0.4. The component is designed for surface mount installation and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

Dual-phase architecture for synchronized buck conversion
Integrated synchronous rectification for enhanced efficiency
Supports phase control and frequency control mechanisms
Includes built-in soft start functionality

Applications

General purpose DC-DC step-down power supplies
Embedded system voltage regulation
Industrial control power distribution

Procurement Notes

This component has reached end-of-life status and is no longer manufactured by Diodes Incorporated. Verification of current availability should focus on identifying qualified replacement parts or checking remaining stock from authorized distributors. Designers must confirm that any substitute components meet the original electrical specifications and thermal requirements before integration into production systems.

Selection Notes

Engineers selecting this part should note its discontinuation status. The dual-phase synchronous buck topology requires careful layout considerations for high-current paths. The U-QFN4040-24 package necessitates adequate thermal dissipation strategies due to the bare pad design. Compatibility with external MOSFETs and passive components must be verified against the specific application's load and input voltage conditions.

Part Context

The AP3595 belongs to the AP3595 series of power management integrated circuits from Diodes Incorporated. This series focuses on efficient power conversion solutions for modern electronic devices. The FNTR-G1 suffix indicates the specific tape and reel packaging variant with lead-free and halogen-free compliance, aligning with environmental standards for consumer and industrial electronics manufacturing.
