LT8631HFE#PBF

Overview

The LT8631HFE#PBF is a synchronous step-down DC/DC converter featuring an internal current-mode PWM controller and integrated power switches. It supports a wide input voltage range of 3V to 100V, enabling operation from various automotive, industrial, and telecom power sources. The device delivers up to 1A of output current with selectable switching frequencies of 400kHz or 1MHz. This flexibility allows for optimized trade-offs between component size and efficiency across diverse application requirements.

Feature Summary

Integrates high-side and low-side synchronous switches for efficient power conversion
Supports wide input voltage ranges suitable for automotive and industrial systems
Offers selectable switching frequencies to optimize external component selection

Applications

Automotive electronics and infotainment systems
Industrial control and instrumentation power supplies
Telecommunications equipment requiring 36V to 72V regulation

Procurement Notes

Verify the suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the package type matches the required PCB footprint. Ensure the specific frequency variant aligns with the design's inductor and capacitor selections. Cross-reference the manufacturer datasheet for thermal performance limits under expected load conditions.

Selection Notes

Select this component when a wide input voltage range exceeding standard 40V limits is required. The integrated synchronous rectification reduces external component count compared to controllers. Consider the 1MHz option for minimizing passive component size, or the 400kHz option for potentially higher efficiency at light loads. Evaluate thermal dissipation capabilities based on the maximum expected output current.

Part Context

The LT8631 series belongs to Analog Devices' portfolio of micropower synchronous step-down regulators. These devices are designed for applications demanding high efficiency and wide input voltage tolerance. The HFE#PBF designation specifies a particular pinout and package configuration within the broader LT8631 family, ensuring compatibility with specific board layouts.

Replacement Considerations

LT8631EFE#PBF: Offers similar functionality with potential differences in switching frequency options or package variations. Verify electrical parameters and pin compatibility before substitution.
