LM26400YMH/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM26400YMH/NOPB is a dual-output synchronous buck regulator from Texas Instruments, designed for wide input voltage applications. It integrates two independent 2A channels within a single 16-pin HTSSOP package with an exposed pad. The device operates with an input range of 3V to 20V and provides adjustable output voltages from 0.6V to 16V per channel. It features a fixed switching frequency of 500kHz, enabling the use of small external inductors and capacitors. The regulator supports parallel operation for increased current capability and includes comprehensive protection features such as overcurrent, thermal shutdown, and soft-start functionality.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix against the manufacturer's latest datasheet to ensure compatibility with specific thermal or electrical requirements. Confirm that the HTSSOP-16 package footprint matches your PCB design constraints. Check for RoHS compliance status if required by your manufacturing standards. Ensure that the operating temperature range meets your application's environmental conditions before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when dual independent outputs are needed from a single controller to save board space. Consider the 500kHz switching frequency for balancing efficiency and passive component size. Evaluate the total current demand against the 2A per channel limit. Verify input voltage stability to ensure it remains within the 3V to 20V operational window. Assess thermal dissipation needs based on load current and ambient temperature.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to Texas Instruments' LM26400 family of dual buck regulators. It shares core architecture with variants like LM26400YMHX/NOPB, differing primarily in packaging or tape-and-reel configuration. The series targets applications requiring compact, efficient dual-rail power solutions. It complements other TI power management ICs by offering integrated control for two channels.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM26400YMHX/NOPB for identical performance in reel packaging. Cross-reference with LM26400YMH/NOPB for pin-compatible alternatives. Verify that any replacement maintains the 2A per channel rating and 500kHz frequency. Ensure thermal characteristics and control loop stability match the original design requirements.
