LM3492MH/NOPB

Overview

The LM3492MH/NOPB is a two-channel individual dimmable LED driver IC manufactured by Texas Instruments. It utilizes a boost topology and operates within an input voltage range of 4.5 V to 65 V. The device supports adjustable output currents between 50 mA and 200 mA per channel, with an adjustable switching frequency ranging from 200 kHz to 1 MHz. It features PWM dimming capabilities and is housed in an HTSSOP-20 package. The component is rated for operation at temperatures between -40°C and +125°C.

Feature Summary

Provides independent control for two separate LED channels
Supports pulse-width modulation (PWM) dimming functions
Includes integrated thermal shutdown protection mechanisms

Applications

LED lighting driver circuits
General illumination systems requiring dual-channel control

Procurement Notes

Verify the exact part number suffix against official Texas Instruments documentation to ensure correct packaging and temperature grade specifications. Confirm that the HTSSOP-20 package variant matches the design requirements. Cross-reference the datasheet revision history to validate current manufacturing status and any potential form-fit-function changes before finalizing procurement orders.

Selection Notes

Select this component when designing boost converter topologies for LED applications requiring dual-channel independence. Ensure the required output current falls within the 50 mA to 200 mA range. Verify that the operating environment stays within the specified -40°C to +125°C temperature limits. Consider the adjustable switching frequency range for electromagnetic interference management.

Part Context

This device belongs to the LM3492 series of LED drivers from Texas Instruments. It is distinct from other variants such as the LM3492HC or the LM34926/7 regulator series. While sharing the base family name, specific suffixes indicate differences in output current capabilities, packaging, or internal bias regulator integration. This specific model focuses on standard current drive capabilities in a 20-pin package.
