LM2833ZSD/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2833ZSD/NOPB is a synchronous step-down DC-DC converter manufactured by Texas Instruments. It operates with an input voltage range of 3 V to 5.5 V and provides an adjustable output voltage from 0.6 V to 4.5 V. The device delivers a maximum output current of 3 A at a fixed switching frequency of 1.5 MHz. It is housed in a 10-pin MSOP package with an exposed thermal pad, designed for surface-mount installation. The component supports operation across a junction temperature range of -40°C to +125°C and includes integrated shutdown functionality for power management.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix ZSD against the official datasheet to confirm the pinout and package dimensions match the target PCB footprint. Ensure the ordering part number includes the NOPB designation if lead-free compliance is required. Cross-reference the manufacturer's latest revision history to confirm material composition and manufacturing location consistency before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 3 A load current is required within a narrow 3 V to 5.5 V input window. The fixed 1.5 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 10-MSOP package size constraints and thermal requirements for the application environment. Verify that the desired output voltage range falls within the 0.6 V to 4.5 V specification limits.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM283x family of high-efficiency synchronous buck converters. It shares architectural similarities with the LM2831 but offers higher current capability. The family is designed for space-constrained applications requiring robust performance from low-voltage sources. The ZSD suffix indicates a specific tape-and-reel packaging configuration for automated assembly.
