LM2853MH-3.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2853MH-3.0 is a synchronous step-down switching regulator manufactured by Texas Instruments, designed for high-efficiency power conversion in compact spaces. It integrates high-side and low-side N-channel MOSFETs to deliver a fixed 3.0 V output from an input voltage range of 2.7 V to 6.0 V. The device supports a maximum continuous output current of 3 A with a typical switching frequency of 550 kHz. Housed in a 14-pin HTSSOP package, it operates over an extended temperature range of -40°C to +125°C, featuring integrated protection against overcurrent, thermal overload, and undervoltage lockout.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) to confirm lead-free compliance and RoHS status, as packaging variants may differ. Ensure the ordering part number matches the required pin-out and thermal pad configuration for your PCB layout. Cross-reference the datasheet revision date to confirm the latest electrical characteristics and application circuit recommendations before finalizing component selection.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.0 V rail is required with up to 3 A load capability in a space-constrained design. The fixed-frequency operation simplifies external filter component selection compared to variable-frequency alternatives. Consider the thermal performance of the HTSSOP package under full load conditions and ensure adequate copper area for heat dissipation to maintain reliability within the specified operating temperature range.
