Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM22670TJ-5.0/NOPB

LM22670TJ-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22670TJ-5.0/NOPB is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator featuring an integrated power switch. It delivers a fixed 5 V output with a maximum current capacity of 3 A. The device operates within an input voltage range of 4.5 V to 42 V and supports a switching frequency of 500 kHz. It utilizes a TO-263-7 (TO-263) surface-mount package with seven pins. The component functions reliably across an operating temperature range from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a high-efficiency synchronous or non-synchronous power switch for compact design
Supports frequency synchronization to reduce electromagnetic interference in multi-module systems
Includes built-in thermal shutdown and adjustable/fixed current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation in industrial equipment
Power distribution units requiring stable 5 V rails
Embedded systems with wide input voltage variations

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix against the manufacturer datasheet to confirm pinout and thermal pad configuration. Ensure the ordering part number matches the specific package variant required for your PCB footprint. Cross-reference the revision level to guarantee compatibility with existing design files and assembly processes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output at up to 3 A is required from inputs up to 42 V. The TO-263 package offers superior thermal dissipation compared to smaller SMD options. Consider the 500 kHz switching frequency for balancing component size and efficiency requirements in space-constrained applications.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2267x series of SIMPLE SWITCHER regulators, designed for high-efficiency DC-DC conversion.
