LM34922MYX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM34922MYX/NOPB is a step-down switching regulator from Texas Instruments featuring constant on-time (COT) architecture. It operates with an input voltage range up to 28V and delivers a maximum output current of 2A. The device integrates a 1MHz fixed switching frequency and supports adjustable output voltages via external resistors. It utilizes an HVSSOP-10 package for surface mount installation. The component functions within an ambient temperature range of -40°C to +125°C and maintains a typical quiescent current of 1.2mA.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Constant on-time control architecture for fast transient response
• Integrated high-side and low-side power switches
• Fixed 1MHz switching frequency reduces external component size
• Built-in soft-start and thermal shutdown protection

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation in industrial equipment
• Bias supply for FPGA or ASIC logic cores
• General-purpose DC/DC conversion in embedded systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'X' against the manufacturer datasheet to confirm tape-and-reel packaging configuration. Ensure the ordering part number matches the required temperature grade and RoHS compliance status. Cross-reference the HVSSOP-10 footprint dimensions during PCB layout finalization to prevent assembly errors.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact buck converter solution is required for inputs up to 28V. The integrated power switches simplify design by eliminating external MOSFET selection. Consider the 1MHz frequency trade-off between efficiency and passive component size. Verify that the load transient requirements align with the COT control loop stability characteristics.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM34922 family of non-synchronous buck converters. It shares architectural similarities with other TI COT regulators but is distinguished by its 28V absolute maximum rating and 2A current capability. The MYX/NOPB designation indicates a specific commercial grade variant with lead-free packaging.
