AP5002SG-13

Overview

The AP5002SG-13 is a step-down switching regulator with PWM control manufactured by Diodes Incorporated. It integrates a reference voltage source, oscillation circuit, error amplifier, and internal PMOS switch. The device supports an input voltage range of 3.6V to 20V and provides an adjustable output voltage from 0.8V to VCC. It features a typical oscillation frequency of 500KHz, which reduces to 50KHz during over-current or short-circuit protection events. The converter includes soft-start functionality, thermal shutdown, and an enable function. It is housed in an SOP-8L package.

Feature Summary

• Integrates internal PMOS power switch for low external component count
• Provides linear duty ratio variation up to 100% via PWM control
• Includes built-in soft-start to prevent startup overshoot
• Features adaptive frequency reduction during fault conditions

Applications

• PC Motherboard power supply
• LCD Monitor power distribution
• Graphic Card voltage regulation
• Telecom Equipment power systems
• Microprocessor core supply

Procurement Notes

Verify the specific suffix SG-13 against the manufacturer's current datasheet to confirm package type and environmental compliance status. Ensure the ordering information matches the exact part number required for your Bill of Materials. Cross-reference the RoHS compliance details provided in the official documentation prior to final procurement decisions.

Selection Notes

Select this component for applications requiring high efficiency and low ripple power delivery within a 3.6V to 20V input range. The integrated compensation block minimizes external component requirements. Consider the 500KHz switching frequency for balancing size and performance. Ensure load currents remain within the internal PMOS limits and utilize MLCC capacitors for optimal stability.
