LT3048EDC-12#TRMPBF

Overview

The LT3048EDC-12#TRMPBF is a dual-output power management IC from Analog Devices, integrating a 2.2 MHz synchronous boost converter and a low-dropout linear regulator in an 8-lead DFN package. The boost stage provides a fixed 13.1 V output at up to 300 mA, while the LDO delivers a fixed 12 V output at 45 mA. It operates within a 2.7 V to 4.8 V input voltage range and supports a shutdown function. The device functions reliably across an extended temperature range of -40°C to +125°C.

Feature Summary

• Integrates a high-efficiency synchronous boost converter with a precision low-noise LDO for combined power generation and regulation.
• Features a fixed 2.2 MHz switching frequency that allows for the use of compact external components.
• Includes a dedicated shutdown pin to minimize quiescent current consumption during standby modes.

Applications

• Biasing circuits for analog-to-digital converters requiring clean, stable supply rails.
• Powering operational amplifiers and sensor interfaces in portable instrumentation.
• Generating auxiliary voltages for microcontrollers and communication modules in battery-operated devices.

Procurement Notes

Verify the complete part number including the suffix #TRMPBF to ensure correct reel packaging and tape specifications. Confirm that the DC-1211A or similar evaluation kits are available if hardware validation is required before production integration.

Selection Notes

Select this component when a single solution is needed to generate a higher bus voltage and simultaneously provide a regulated lower voltage. Ensure the input source can sustain the peak currents required by the boost converter without dropping below the minimum operating threshold.

Part Context

This part belongs to the LT3048 series, which combines switching and linear technologies. It differs from other variants primarily through its specific output voltage settings and the TRMPBF suffix indicating tape-and-reel packaging for automated assembly processes.
