AP3842GP-E1

Overview

The AP3842GP-E1 is an integrated offline switch manufactured by Diodes Incorporated, designed for AC-DC conversion applications. It operates at a switching frequency of 52kHz and supports a maximum power output of 1W. The device features a fixed startup voltage of 16V and requires a supply voltage of 10V. It achieves a duty cycle of 96% and incorporates comprehensive fault protection mechanisms including current limiting, overload protection, and overtemperature shutdown. The component is housed in an 8-PDIP package with a standard DIP footprint.

Feature Summary

• Integrated offline switch topology for non-isolated AC-DC conversion
• Built-in protection against current limits, overloads, and overheating
• Fixed frequency control operation for stable power management

Applications

• Offline AC-DC converter circuits
• Low-power isolated power supply designs
• Consumer electronics power adapters

Procurement Notes

Verify the specific suffix 'E1' to ensure compliance with RoHS standards and REACH regulations as documented. Confirm that the 8-DIP package matches the target PCB layout requirements. Check the product status carefully, as this item may be classified as obsolete or end-of-life depending on the current date relative to the manufacturer's discontinuation notices. Ensure the supplier provides valid traceability documentation for the component batch.

Selection Notes

Select this component when a simple, cost-effective solution for low-power offline applications is required. The integrated nature eliminates the need for external discrete switches. Consider the 52kHz frequency for EMI considerations. Verify that the 1W power limit meets the system load requirements. The PDIP package is suitable for through-hole assembly processes. Evaluate thermal performance within the specified -40°C to 85°C operating range.

Part Context

This part belongs to the AP3842 series from Diodes Incorporated, categorized under Power Management ICs (PMIC). It functions as a switching controller/offline switch. The series is designed for general-purpose power conversion tasks. The GP variant specifically denotes the package and material configuration within the broader product line. It competes in the market for basic offline power regulation components.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The AP3842CP-E1 is listed as a related variant with similar specifications but a slightly different duty cycle (97%). Verification of pinout compatibility and electrical parameter equivalence is required before considering any cross-referencing with other manufacturers' parts.
