AP4340LNTR-G1

Power Management - Specialized Overview

The AP4340LNTR-G1 is a Power Supply Regulator (PMIC) designed as a PSR Accelerator for AC/DC applications. Manufactured by Diodes Incorporated, it operates within a supply voltage range of 5V and draws a supply current of 240µA. The device functions across an operating temperature range of -40°C to 85°C. It is housed in a surface-mount SOT-23-3 package, specifically identified as TO-236-3 or SC-59. This component serves as a specialized detector for dynamic primary-side regulation systems.

Power Management - Specialized Feature Summary

• Functions as a dedicated PSR accelerator for AC/DC power supplies
• Provides dynamic detection capabilities for primary-side regulation circuits
• Utilizes a compact SOT-23-3 surface-mount package for space-constrained designs

Power Management - Specialized Applications

• AC/DC converter systems requiring primary-side regulation
• Power supply units utilizing PSR accelerator technology
• Dynamic detection circuits in isolated power converters

Power Management - Specialized Procurement Notes

Verify component status carefully as the AP4340 series may be classified as obsolete or end-of-life in certain distributor catalogs. Confirm availability through official Diodes Incorporated channels or authorized partners. Ensure the specific suffix matches project requirements. Check RoHS compliance documentation prior to integration. Validate that the SOT-23-3 footprint aligns with existing PCB layouts.

Power Management - Specialized Selection Notes

Select this component for applications requiring a dedicated PSR accelerator rather than a complete controller IC. Consider the low supply current of 240µA for efficiency-sensitive designs. Verify compatibility with the target AC/DC topology. The SOT-23-3 package limits pin count, so ensure interface requirements match the three-terminal configuration. Evaluate thermal performance within the specified -40°C to 85°C range.

Power Management - Specialized Part Context

This part belongs to the AP4340 family from Diodes Incorporated, categorized under PMIC and Supervisory Circuits. It is distinct from display drivers or general switching controllers found in other AP series products. The component specifically addresses the acceleration and detection needs in primary-side regulated flyback converters, differentiating it from standard voltage supervisors.
