Overview
The AP3843GP-G1 is an offline switcher 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 startup voltage of 16V and requires a supply voltage (Vcc/Vdd) of 10V. It offers a duty cycle capability of 96% and includes comprehensive fault protection mechanisms such as current limiting, overload protection, and overtemperature shutdown. The component is housed in an 8-PDIP package with through-hole mounting and functions within a temperature range of -40°C to 85°C.
Feature Summary
- Integrated current-mode control for stable operation
- Built-in protection against overcurrent, overload, and overheating conditions
- Fixed frequency switching for simplified filter design
Applications
- Low-power offline AC-DC converters
- Standby power supplies
- Adapter circuits for consumer electronics
Procurement Notes
Verify the specific suffix G1 for RoHS compliance status. Confirm availability as the product may be subject to end-of-life notices or discontinuation. Check for alternative packages if DIP form factor is unavailable. Ensure compatibility with existing PCB footprints before finalizing procurement decisions.
Selection Notes
Select this component for low-power isolated power supply designs requiring simple current-mode control. Consider the 8-DIP package for through-hole assembly requirements. Evaluate thermal management needs given the 85°C operating limit. Compare against similar offline switches if higher power or different packaging is required.
Part Context
This part belongs to the AP3843 series of offline switchers from Diodes Incorporated. It is related to variants like AP3842 and AP3843CM, differing primarily in packaging and minor electrical characteristics. The series targets cost-sensitive, low-power applications where simplicity and reliability are prioritized over high efficiency or advanced digital control features.
Replacement Considerations
Check for direct pin-compatible substitutes within the same manufacturer's portfolio. Verify equivalent switching frequency and fault protection levels when selecting alternatives.
