Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2734ZQMKX/NOPB

LM2734ZQMKX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2734ZQMKX/NOPB is a synchronous step-down (buck) switching regulator from Texas Instruments, designed for high-efficiency power conversion in automotive systems. It operates with an input voltage range of 3 V to 20 V and provides an adjustable output voltage from 800 mV to 18 V. The device delivers up to 1 A of output current and supports a fixed switching frequency of 3 MHz. It is qualified under the AEC-Q100 standard for automotive applications and functions within a junction temperature range of -40°C to +150°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Synchronous buck topology ensures high efficiency across load ranges
AEC-Q100 qualification suitable for demanding automotive environments
Integrated 3 MHz switching frequency enables compact external component sizing

Voltage Regulators - DC DC Switching Regulators Applications

Automotive infotainment system power distribution
Telematics control unit voltage regulation
Body control module power supply conditioning

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'Q' indicates AEC-Q100 automotive qualification status against the official datasheet. Confirm the package type matches SOT-23-THIN requirements for your PCB layout. Ensure the operating temperature range aligns with your system's thermal design specifications before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing for automotive applications requiring robust voltage regulation under wide input variations. The 3 MHz frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Verify that the 1 A current limit meets the peak load demands of the downstream circuitry without triggering protection modes.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2734 family of synchronous buck converters. It shares architectural similarities with other members like the LM2734ZSD/NOPB but differs in packaging and automotive qualification. The QMKX suffix denotes the specific tape-and-reel packaging and automotive grade variant within the broader product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2734ZSD/NOPB offers similar electrical performance but lacks automotive qualification. LM27341 series devices provide higher current capacity but operate at different frequencies.
