Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM26420YMHX/NOPB

LM26420YMHX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM26420YMHX/NOPB is a dual synchronous step-down DC-DC converter manufactured by Texas Instruments. It operates with an input voltage range of 3V to 5.5V and provides two independent adjustable output channels, each capable of delivering up to 2A. The outputs are regulated between 0.8V and 4.5V. The device utilizes a fixed 2.2MHz switching frequency and is housed in a 20-pin HTSSOP package with an exposed pad (EP). It is designed for high efficiency and includes integrated protection features.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Dual-channel synchronous buck topology for independent power rail generation
Automotive-grade qualification ensuring reliability in demanding environments
High-frequency operation enabling compact external component sizing
Integrated thermal and current overload protection mechanisms

Voltage Regulators - DC DC Switching Regulators Applications

Automotive infotainment systems requiring multiple stable voltage rails
Advanced Driver Assistance Systems (ADAS) power distribution
On-board charging and telematics control units
General automotive electronic control modules

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against the official datasheet to confirm package type and temperature grade. Ensure the ordering part number matches the required automotive qualification level. Cross-reference the manufacturer's latest documentation for any pinout or electrical specification updates prior to final procurement decisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing automotive circuits requiring two isolated 2A outputs from a single 12V nominal source. The 20-pin HTSSOP package suits applications where board space allows for larger footprints compared to WQFN options. Consider the 2.2MHz frequency trade-off between component size and electromagnetic interference levels.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM26420 family of dual synchronous DC-DC converters. It shares functional similarities with other automotive PMICs but is distinct in its dual 2A channel configuration and HTSSOP packaging variant. It complements single-channel regulators like the LM26001 for more complex multi-rail requirements.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM26420Q1XSQX/NOPB and LM26420Q1XSQ/NOPB. Note that these alternatives utilize a 16-WQFN package rather than the 20-pin HTSSOP form factor. PCB layout redesign is necessary due to the difference in footprint and pin configuration.
