Overview
The AP5100WG-7 is a synchronous buck switching regulator manufactured by Diodes Incorporated. It operates with an input voltage range of 4.75 V to 24 V and delivers up to 1.2 A output current. The device features a fixed 1.4 MHz switching frequency and supports adjustable output voltages from 800 mV to 15 V. It utilizes a SOT-26-6 surface-mount package and functions within a temperature range of -25°C to +85°C.
Feature Summary
- Integrates synchronous rectification for improved efficiency in step-down conversion applications.
- Utilizes a fixed high-frequency switching architecture to minimize external component size.
- Includes internal protection mechanisms against thermal overload and overcurrent conditions.
Applications
- Portable battery-powered consumer electronics
- Embedded systems requiring regulated low-voltage power rails
- Industrial control modules with wide input voltage ranges
Procurement Notes
Verify the specific suffix 'WG-7' matches the required SOT-26-6 package variant during procurement. Confirm RoHS compliance status through official manufacturer documentation or certified datasheets prior to integration. Ensure that the ordering information aligns with the exact part number to avoid discrepancies in pinout or electrical characteristics.
Selection Notes
Select this component when a compact solution is needed for converting higher input voltages down to stable lower levels. The 1.4 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 1.2 A current limit and 24 V maximum input rating to ensure adequate headroom for the target application's peak load requirements.
Part Context
This part belongs to the AP5100 series of DC-DC converters from Diodes Incorporated. It is categorized under PMIC (Power Management Integrated Circuits) specifically as a voltage converter. The series is designed for space-constrained designs requiring efficient power regulation in small form-factor packages.
Replacement Considerations
Consult official substitution guides for compatible parts within the same product family. Verify pin compatibility and electrical specifications before replacing existing components in established designs.
