AP3706P-E1

Overview

The AP3706P-E1 is a primary side control integrated circuit designed for offline battery chargers, manufactured by Diodes Incorporated. It utilizes flyback topology and operates within a supply voltage range of 7.3V to 30V. The device incorporates internal fault protection mechanisms including open circuit, overvoltage, and short circuit safeguards. It features an 8-SOIC package with a width of 3.90mm and supports surface mount installation. The component functions without an internal switch and includes a startup voltage threshold of 18.5V. It is rated for operation between -40°C and 85°C.

Feature Summary

Primary side control architecture for isolated offline applications
Integrated fault protection against open, overvoltage, and short circuit conditions
Flyback converter topology support

Applications

Offline battery charger systems
Isolated power supply designs
Flyback converter implementations

Procurement Notes

Verify the specific suffix P-E1 against official Diodes Incorporated documentation to confirm pinout and electrical characteristics, as variations exist within the AP3706 family. Confirm current availability status as some variants are marked end-of-life. Ensure compliance with RoHS3 and REACH requirements for the intended market. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component for applications requiring primary-side regulation in offline battery charging circuits. Consider the 8-SOIC package constraints for PCB layout. Evaluate the 18.5V startup threshold against the available input voltage rails. Verify thermal performance within the specified operating temperature range. Compare against other primary-side controllers if internal switching capability or different topologies are required.

Part Context

The AP3706 series consists of primary side control ICs for offline battery chargers. Variants include M-E1, P-E1, and MTR-G1. These devices are classified under PMIC AC DC converters and offline switching regulators. They are distinct from general-purpose switching devices or LED drivers found in similar product categories.
