Overview
The AP2008SG-13 is a Buck switching regulator controller manufactured by Diodes Incorporated. It integrates Pulse-Width-Modulation (PWM) control circuitry into a single chip, designed primarily for power-supply regulation applications. The device operates within an input voltage range of 4.5V to 27V and supports a switching frequency of 300kHz. It features voltage-mode control architecture and is housed in an 8-pin SOIC package with tape and reel packaging.
Feature Summary
- Integrates PWM control circuitry for compact power supply design
- Supports voltage-mode control architecture for stable regulation
- Designed specifically for buck converter topologies
Applications
- Power-supply regulators
- Buck converter circuits
- Voltage regulation systems
Procurement Notes
Verify the component status as active before procurement. Confirm that the specific suffix 'SG-13' corresponds to the required 8-SOIC package and tape-and-reel quantity. Ensure compatibility with standard surface-mount assembly processes. Cross-reference the manufacturer part number against official Diodes Incorporated documentation to confirm current availability and compliance with RoHS standards.
Selection Notes
Select this controller when a dedicated voltage-mode solution for buck applications is required. The integrated PWM functionality reduces external component count compared to discrete solutions. Consider the 300kHz fixed switching frequency for EMI and efficiency trade-offs. Ensure the input voltage range aligns with the system's power source requirements.
Part Context
This component belongs to Diodes Incorporated's portfolio of power management devices. It is categorized under switching regulators and controllers. The product line targets industrial and general-purpose power supply applications where efficient voltage step-down is necessary. It complements other Diodes products like MOSFETs and diodes in complete power stage designs.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical specifications carefully if considering alternatives from other manufacturers.
