Key Features
- Synchronous 3 A buck regulator with integrated high-side and low-side MOSFETs eliminating external Schottky diode for improved efficiency
- Fixed 0.8 V output voltage ideal for powering low-core-voltage FPGAs, DSPs, and processor core supplies directly
- Wide input voltage range of 3 V to 5.5 V compatible with 3.3 V and 5 V power rails in embedded and telecom systems
- Voltage-mode PWM control with 14-pin SOIC package enabling simple, stable external compensation and compact PCB layout
Applications
The LM2853MH-0.8 is designed for point-of-load power conversion in systems requiring a stable 0.8 V core supply from a 3.3 V or 5 V intermediate bus, such as FPGA core rails, DSP core power supplies, and low-voltage processor power domains. It is well-suited for networking equipment, data communication boards, and embedded computing modules where high-efficiency synchronous buck conversion with 3 A capability is needed. Its compact 14-pin SOIC footprint also makes it practical for space-constrained industrial control and instrumentation power stages.

Frequently Asked Questions
What is the output voltage and current rating of the LM2853MH-0.8?
The LM2853MH-0.8 provides a fixed 0.8 V output voltage at up to 3 A continuous output current, making it specifically designed to power low-core-voltage digital ICs such as FPGAs, DSPs, and processor cores that require sub-1 V supply rails.
What input voltage range does the LM2853MH-0.8 support?
The LM2853MH-0.8 operates from an input voltage range of 3 V to 5.5 V with a nominal 5 V design point, allowing it to accept both 3.3 V and 5 V intermediate bus voltages commonly found in embedded computing and networking system power architectures.
What are the advantages of the synchronous architecture in the LM2853MH-0.8?
The synchronous buck architecture integrates both high-side and low-side power MOSFETs, eliminating the need for an external Schottky rectifier diode. This reduces component count, improves power conversion efficiency especially at high output currents, and simplifies PCB layout compared to non-synchronous regulators.
What package does the LM2853MH-0.8 use?
The LM2853MH-0.8 is housed in a 14-pin SOIC package (JESD-30 code R-PDSO-G14), which is a standard surface-mount outline providing a good balance between PCB footprint area, thermal dissipation capability, and ease of soldering in production environments.
Is the LM2853MH-0.8 RoHS compliant?
The LM2853MH-0.8 carries a JESD-609 code of e0, indicating it is a leaded (non-lead-free) component and is not RoHS compliant. Designers requiring lead-free alternatives for RoHS-regulated products should consider a pin-compatible lead-free replacement from the LM2853 family.
