LTM8049EY#PBF

Product Overview

The Analog Devices Inc. LTM8049EY#PBF is a non-isolated PoL DC-DC converter module intended for board-mount power conversion. It provides two outputs: a positive output specified from 2.5 V to 24 V and a negative output specified from -2.5 V to -24 V. The input operating range is 2.6 V to 20 V, and the maximum output current is 1 A. The module uses a 77-BBGA surface-mount package measuring 15.0 mm x 9.0 mm x 2.4 mm, and it has a specified operating temperature range of -40°C to 125°C.

Key Features

• Non-isolated PoL module with two output channels.
• Positive output range: 2.5 V to 24 V.
• Negative output range: -2.5 V to -24 V.
• Input voltage range: 2.6 V to 20 V.
• Maximum output current: 1 A.
• OTP and UVLO features.
• Surface-mount 77-BBGA package, 15.0 mm x 9.0 mm x 2.4 mm.
• Operating temperature range: -40°C to 125°C.

Applications

• Commercial information technology equipment requiring local non-isolated power conversion.
• Board-level power architectures requiring a positive and a negative output rail.

Design & Procurement Notes

When using this module, verify that the available input rail remains within 2.6 V to 20 V and that the required positive and negative outputs fall within the specified output ranges. The 1 A maximum output current should be assessed against the load profile for each output. Because the device is a surface-mount 77-BBGA module with a 15.0 mm x 9.0 mm x 2.4 mm footprint, board layout, thermal path, and assembly process compatibility should be considered. The specified -40°C to 125°C operating range, OTP, and UVLO should be evaluated against the expected ambient and input-voltage conditions.
