Overview
The AL17052V5W5-7 is a switch-mode AC/DC power supply controller manufactured by Diodes Incorporated. It utilizes primary-side regulation (PSR) topology to provide a fixed 5 V output with a maximum current of 50 mA. The device operates within an extended temperature range from -40 °C to +105 °C and features a low quiescent current of 88 µA. It functions at a switching frequency of 33 kHz and is housed in a compact SOT-25-5 surface-mount package.
Feature Summary
- Implements primary-side regulation for simplified transformer design and reduced component count
- Provides fixed 5 V output suitable for low-power adapter applications
- Operates with low standby power consumption via reduced quiescent current
Applications
- Low-power AC/DC adapters
- Standby power supplies
- Consumer electronics chargers
Procurement Notes
Verify the specific suffix W5-7 against the manufacturer's latest datasheet to confirm packaging details and revision status. Ensure compatibility with required isolation standards for the target application. Cross-reference the Mouser number 621-al17052v5w5-7 for accurate sourcing information.
Selection Notes
Select this component for designs requiring cost-effective, non-isolated or isolated low-power AC/DC conversion without secondary-side feedback components. The PSR architecture eliminates the need for optocouplers and TL431 references, simplifying the bill of materials while maintaining adequate regulation for standard consumer loads.
Part Context
This part belongs to the AL17052 series of AC/DC controllers from Diodes Incorporated. It is designed as a drop-in solution for general-purpose power adapters, offering a balance between performance and simplicity. The SOT-25-5 package allows for space-constrained PCB layouts typical in modern consumer electronics.
Replacement Considerations
Consult official substitution guides for equivalent PSR controllers. Verify pinout compatibility and thermal characteristics before replacing with alternative manufacturers' parts.
