Overview
The AP64200SP-13 is a high-voltage synchronous buck converter from Diodes Incorporated, housed in an SO-EP-8 package. It operates with an input voltage range of 3.8 V to 40 V and provides an adjustable output voltage from 800 mV to 40 V. The device supports a maximum output current of 2 A and features a switching frequency range of 100 kHz to 2.2 MHz. Quiescent current is specified at 25 uA, with operation supported across a temperature range of -40 C to +125 C.
Feature Summary
- Integrates high-side and low-side power MOSFETs for efficient synchronous rectification within a compact surface-mount package.
- Features adjustable switching frequency capability to optimize external component size and system performance.
- Includes comprehensive protection mechanisms such as over-current protection, thermal shutdown, and undervoltage lockout.
Applications
- Industrial control systems requiring robust power regulation
- Automotive electronics compatible with standard voltage architectures
- Point-of-load conversion for embedded computing modules
Procurement Notes
Verify the specific suffix SP-13 against the manufacturer datasheet to confirm tape-and-reel packaging quantities and RoHS compliance status. Ensure the SO-EP-8 footprint matches the target PCB layout. Confirm that the application environment remains within the specified -40 C to +125 C operating temperature range for reliable performance.
Selection Notes
Select this component when a wide input voltage range up to 40 V is required alongside high efficiency in a small form factor. The adjustable frequency feature allows designers to balance between electromagnetic interference filtering requirements and passive component volume. Verify that the load current does not exceed the rated 2 A limit under all thermal conditions.
Part Context
This part belongs to the AP64200 series of high-voltage DC-DC converters manufactured by Diodes Incorporated. The series is designed for applications demanding high reliability and efficiency. The SO-EP-8 package variant offers enhanced thermal dissipation capabilities compared to standard packages, supporting stable operation in dense circuit designs.
Replacement Considerations
The AP64202QSP-13 is a related automotive-grade variant within the same family. Both share similar electrical characteristics but differ in qualification standards. Verify pin compatibility and thermal requirements before substitution.
