LM2736YMK/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2736YMK/NOPB is a synchronous step-down DC-DC converter manufactured by Texas Instruments. It operates with an input voltage range of 3V to 18V and provides a single adjustable output from 1.25V to 16V, supporting up to 750mA load current. The device integrates a 550kHz switching frequency and features low quiescent current for efficiency. Packaged in a compact SOT-23-THIN (TSOT-23-6) housing, it supports junction temperatures from -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates synchronous rectification for high efficiency without external Schottky diodes
• Features fixed 550kHz switching frequency to minimize passive component size
• Includes internal soft-start to limit inrush current during startup
• Provides thermal shutdown protection for system reliability

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered equipment
• Embedded systems requiring efficient voltage regulation
• Industrial control modules

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free/RoHS compliance as per Texas Instruments documentation. Confirm package marking details against the latest datasheet revision. Check for obsolescence notices or PCN updates regarding pin marking changes. Ensure compatibility with existing PCB footprints for the SOT-23-THIN-6 package before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact synchronous buck solution is required for inputs up to 18V. It is suitable for designs prioritizing board space savings over maximum current capacity. Compare against non-synchronous alternatives if cost is the primary driver, noting that synchronous versions offer higher efficiency at moderate loads. Verify that the 750mA output current meets the specific application requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2736 family of synchronous step-down converters. It shares functional similarities with the LM2734 but differs in output current capabilities and specific integration features. The 'YMK' designation refers to the TSOT-23-6 thin package variant, while 'NOPB' signifies the lead-free and RoHS-compliant version produced by Texas Instruments.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2736XMK/NOPB is a documented alternative within the same family, offering identical functionality in the same package. Verify pinout compatibility and electrical specifications before substitution.
