AP5001SG-13

Overview

The AP5001SG-13 is a PWM-controlled step-down DC-DC converter manufactured by Diodes Incorporated. It integrates an internal P-channel MOSFET switch and supports an input voltage range of 3.6V to 20V with an output voltage adjustable from 0.8V up to the supply voltage. The device delivers a continuous output current of 1.5A at a typical oscillation frequency of 800kHz. Key protection features include soft-start, current limiting, thermal shutdown, and an enable function. It is designed for low ESR output capacitors such as MLCCs and is housed in a lead-free, RoHS-compliant SOP-8L package.

Feature Summary

• Integrates an internal P-channel MOSFET switch to minimize external component count
• Provides comprehensive protection via built-in soft-start, current limit, and thermal shutdown functions
• Supports low ESR output capacitors including multi-layer ceramic capacitors (MLCCs)
• Features an enable pin for power management control

Applications

• PC motherboard power distribution
• LCD monitor power supplies
• Graphic card voltage regulation
• Telecom equipment power systems
• Microprocessor core supply circuits

Procurement Notes

Verify the specific suffix 'SG-13' against the manufacturer's latest datasheet to confirm packaging details and environmental compliance status. Ensure the design accounts for the SOP-8L package thermal characteristics during operation. Cross-reference the part number with official Diodes Incorporated documentation to validate availability and any recent product change notifications before finalizing procurement plans.

Selection Notes

Select this component for applications requiring a compact, non-synchronous buck solution with integrated switching capabilities. The fixed 800kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 1.5A current limit when designing for peak load conditions. Verify that the required output voltage range falls within the 0.8V to VCC specification limits for stable regulation.

Part Context

This part belongs to the AP5001 series of step-down converters from Diodes Incorporated. It shares functional similarities with other members like the AP5002 but offers a 1.5A output rating compared to higher current variants. The SOP-8L package provides a space-efficient footprint suitable for dense PCB layouts in consumer electronics and industrial control boards.
