Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM34923MM/NOPB

LM34923MM/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM34923MM/NOPB is an 80-V, 600-mA constant on-time buck switching regulator from Texas Instruments. It integrates an 80-V N-channel power switch and supports adjustable output voltages. The device operates with a fixed switching frequency and includes features for efficient bias regulation in high-voltage applications.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates an 80-V N-channel buck switch for compact design
Utilizes constant on-time control architecture for fast transient response
Supports adjustable output voltage configuration

Voltage Regulators - DC DC Switching Regulators Applications

High-voltage bias regulation
Point-of-load conversion
Industrial power systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the package type is MSOP-10 and confirm the suffix NOPB indicates lead-free and RoHS compliance. Ensure the operating temperature range meets system requirements of -40°C to +125°C. Cross-reference the manufacturer part number with official Texas Instruments documentation to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring an integrated high-voltage buck solution with moderate current capability. The constant on-time topology offers simplicity in external component selection. Compare against the LM34926 series if higher input voltage or different current ratings are required.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3492x family of high-voltage buck regulators. It shares architectural similarities with the LM34926 but differs in voltage rating (80V vs 100V) and current capacity (600mA vs 300mA). The MM package denotes a small-outline micro-package suitable for space-constrained designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM34926MR/NOPB is a related high-voltage regulator but operates at 100V and 300mA. Verify that the lower current rating of the LM34923 does not impact load requirements before substitution.
