Overview
The LT3048IDC-15#TRMPBF is a dual-output power management IC from Analog Devices, combining a boost switching regulator and an LDO in an 8-DFN package. It operates with an input voltage range of 2.7 V to 4.8 V and features a 2.2 MHz switching frequency. The first output provides 16.1 V at 300 mA, while the second delivers 15 V at 45 mA. Designed for industrial applications, it functions within a temperature range of -40°C to +125°C.
Feature Summary
- Integrates a high-current boost converter and a low-noise LDO into a single compact component.
- Provides independent regulation for two distinct output rails simultaneously.
- Supports wide operating temperature ranges suitable for demanding environments.
Applications
- Bias generation circuits requiring multiple voltage levels
- Industrial sensor interface power supplies
- Embedded systems with mixed analog and digital power requirements
Procurement Notes
Verify the specific suffix #TRMPBF against official documentation to confirm tape-and-reel packaging details. Confirm that the ID variant meets the required industrial temperature specifications for your design. Cross-reference the manufacturer's latest datasheet to ensure compatibility with your system's input voltage constraints before finalizing procurement.
Selection Notes
Select this component when a combined boost and linear regulation solution is needed within a small footprint. Ensure the input voltage stays within the 2.7 V to 4.8 V range. Verify that the thermal performance of the 8-DFN package suits the expected power dissipation in the target application environment.
Part Context
This part belongs to the LT3048 series, which integrates switching and linear regulators. It differs from other variants by its specific output voltages and industrial temperature grade. The DC suffix indicates the DFN package type, while IDC specifies the industrial temperature range classification within the product family.
Replacement Considerations
LT3048EDC-15#TRMPBF offers similar functionality but may differ in temperature rating or manufacturing lot specifications. Verify pinout compatibility and electrical parameters against the official datasheet before substitution.
