Overview
The AL1678DMTR-G1 is a non-isolated AC/DC converter and primary side controller manufactured by Diodes Incorporated. It operates within an input voltage range of -300 mV to 22 V and delivers up to 5 W of output power. The device utilizes Silicon technology and features a switching frequency of 60 kHz with a typical operating supply current of 435 uA. Designed for surface mount applications, it is housed in an SO-7 package and supports one output. The component functions across a temperature range of -40 C to +85 C.
Feature Summary
- Primary side control architecture for non-isolated AC/DC conversion
- Integrated silicon-based switching capability at 60 kHz
- Single output configuration with low standby current consumption
Applications
- Low power AC/DC power supply designs
- Offline driver circuits for consumer electronics
- Non-isolated power management systems
Procurement Notes
Verify the current lifecycle status as the component is listed as discontinued or end-of-life. Confirm availability through authorized distributors or secondary market channels, as standard stock may be limited. Ensure that the SO-7 package and pinout match your existing design requirements before procurement. Check RoHS compliance details and verify that the specific suffix corresponds to the required reel or cut tape packaging format.
Selection Notes
Select this component for applications requiring simple primary-side regulation without optocouplers. The 5 W power limit and 60 kHz frequency suit compact, cost-sensitive designs. Consider the SO-7 package size for space-constrained PCB layouts. Evaluate the -40 C to +85 C operating range against environmental conditions. Compare the 435 uA supply current against efficiency targets for low-power standby modes.
Part Context
This part belongs to the AP3968 series family from Diodes Incorporated, categorized under PMIC - Power Management ICs. It serves as an AC/DC converter solution, distinct from the PFC LED drivers like the AL1678 or AP1662 found in similar catalogs. The component represents a specific implementation of primary-side controlled power conversion technology.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the item is marked as discontinued, alternative sourcing requires verification of functional equivalents through official manufacturer cross-reference tools.
