KTB8370BEIB-5C-TR

Voltage Regulators - DC DC Switching Regulators Overview

The KTB8370BEIB-5C-TR is a synchronous buck switching regulator IC manufactured by Kinetic Technologies. It features an input voltage range of 4.7V to 17V and delivers a fixed output voltage of 3.3V with a maximum output current of 5A. The device operates at a switching frequency of 500kHz and utilizes Adaptive On-Time (AOT) control for enhanced transient response. It is housed in a 20-WFBGA or WLCSP package, suitable for surface mount installation, and supports an operating temperature range from -40°C to +150°C junction temperature.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific package variant (WFBGA vs WLCSP) as indicated in the ordering information, since both are referenced in available documentation. Confirm that the fixed 3.3V output aligns with system requirements, as other variants in the series offer different voltages. Ensure compatibility with the 500kHz switching frequency for filter component selection. Check RoHS compliance status through official manufacturer channels before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required within a 4.7V to 17V input range. The 5A current capacity suits moderate power applications. Consider the AOT control for simpler compensation design compared to voltage mode controllers. Evaluate thermal performance given the 150°C junction rating. Compare against adjustable variants if flexible output voltage is needed instead of the fixed configuration.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the Kinetic Technologies KTB8370 series of synchronous buck regulators. The series is characterized by its use of Adaptive On-Time control, which simplifies external component selection and improves transient response. Other members of the series include variants with different output voltages such as 5.0V, but share similar input ranges and control architectures.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes may include other 5A synchronous buck regulators with similar input ranges and AOT control. Verify pinout compatibility and thermal characteristics. Adjustable output versions like KTB8370BEIB-XX-TR require circuit redesign for voltage setting.
