- Industrial LED panel lighting
Procurement Notes
Verify the specific suffix 'HSP-13' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the design accounts for the exposed pad thermal requirements inherent to the SO-8 EP package. Cross-reference the operating temperature range of -40°C to +105°C with your application environment. Confirm that the 700 kHz switching frequency aligns with your EMI constraints and inductor selection.
Selection Notes
Select this component when a wide input voltage range up to 60 V is required for LED strings. It is suitable for designs needing integrated open-circuit protection without external sensing circuits. Consider the SO-8 EP package for thermal management needs in compact footprints. Evaluate the 1 A output capability against the target LED array current requirements. Verify compatibility with existing PCB layout guidelines for Buck converters.
Part Context
This part belongs to the AP8802 series of LED drivers from Diodes Incorporated. The series includes variants such as the AP8802SPG-13, which shares similar functional characteristics but may differ in maximum voltage ratings or packaging options. These devices are categorized under LED Lighting Drivers within the broader Driver ICs subcategory, targeting efficient power management for solid-state lighting applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer's official replacement guide or contact technical support directly for qualified alternatives. Do not assume cross-compatibility with other manufacturers' parts without verifying electrical parameters and pin configurations.
