Overview
The AP8801SG-13 is a single-channel LED lighting driver IC manufactured by Diodes Incorporated. It operates as a step-down (buck) DC/DC converter with an input voltage range of 8 V to 48 V and a maximum output current of 500 mA. The device features a fixed switching frequency of 625 kHz and supports adjustable output voltages. It includes PWM dimming capabilities and open LED protection. The component functions within a temperature range of -40 °C to +105 °C and is housed in an SOP-8 surface-mount package.
Feature Summary
- Integrates a buck converter topology for efficient LED current regulation
- Supports analog and PWM dimming control methods
- Includes built-in open LED protection circuitry
Applications
- LED lighting driver circuits
- General-purpose DC/DC conversion for low-power loads
Procurement Notes
Verify the specific suffix 'SG-13' against the manufacturer's official datasheet to confirm pinout, thermal characteristics, and RoHS compliance status. Ensure the application circuit design accounts for the specified 625 kHz switching frequency and input voltage limits. Cross-reference the SOP-8 footprint dimensions with your PCB layout guidelines before finalizing procurement.
Selection Notes
Select this component when a compact, single-channel buck regulator is required for LED applications with inputs up to 48 V. It is suitable for designs needing integrated protection against open-load conditions and support for PWM dimming signals. Consider the SOP-8 package constraints and the 625 kHz operating frequency regarding external component selection and thermal management requirements.
Part Context
This part belongs to the AP8801 series from Diodes Incorporated, categorized under PMIC - LED Drivers. It is designed specifically for driving LEDs using a step-down topology. The series targets cost-sensitive and space-constrained lighting solutions requiring reliable current regulation and basic protection features in a standard surface-mount package.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative drivers based on matching buck topology, input voltage range, and current capacity.
