AP2014SG-13

Overview

The AP2014SG-13 is a synchronous buck switching regulator controller manufactured by Diodes Incorporated. It operates within an input voltage range of 4.5V to 28V and supports output voltages from 0.8V to 24V. The device integrates a high-side and low-side driver capable of sourcing and sinking up to 2A peak current. Key electrical parameters include a fixed switching frequency of 300kHz, a quiescent current of 60µA, and an enable threshold of 2.7V. It features comprehensive protection mechanisms including overcurrent, thermal shutdown, and undervoltage lockout.

Feature Summary

• Integrates high-side and low-side drivers with 2A peak current capability for efficient power delivery
• Provides comprehensive protection against overcurrent, thermal overload, and undervoltage conditions
• Supports flexible output voltage configuration via external resistor network down to 0.8V

Applications

• Point-of-load (POL) conversion in industrial equipment
• Power management for embedded systems and microcontrollers
• Battery-powered devices requiring efficient step-down regulation

Procurement Notes

Verify the specific suffix 'SG-13' to confirm the SOIC-8 package variant and tape-and-reel packaging format. Ensure compatibility with the required PCB footprint and soldering profile. Cross-reference the manufacturer's latest datasheet for any updates to pinout definitions or recommended operating conditions before finalizing procurement specifications.

Selection Notes

Select this component when a synchronous buck topology is required for higher efficiency compared to asynchronous designs. It is suitable for applications demanding precise output voltage regulation and robust transient response. Consider the 300kHz switching frequency for balancing component size and electromagnetic interference. Evaluate thermal performance requirements based on the expected load current and ambient temperature conditions.

Part Context

This part belongs to the AP2014 series of synchronous buck regulators from Diodes Incorporated. It is designed as a complete control solution for DC-DC conversion, eliminating the need for external MOSFETs in lower power configurations or driving them directly in higher power setups. The series targets cost-sensitive and space-constrained applications requiring reliable power management.
