LM3370TL-3806/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM3370TL-3806/NOPB is a dual synchronous step-down DC-DC converter manufactured by Texas Instruments. It operates within an input voltage range of 2.7 V to 5.5 V and provides two independent positive fixed output voltages of 1.6 V and 1.8 V. Each channel supports a maximum output current of 600 mA. The device integrates dynamic voltage scaling functionality and switches at a frequency of 2 MHz. It functions reliably across an operating temperature range from -30°C to +85°C and is housed in a 20-WFBGA package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates dual synchronous buck converters with dynamic voltage scaling capability for optimized power efficiency.
• Supports wide input voltage ranges suitable for single-cell lithium-ion battery applications.
• Features compact surface-mount packaging designed for space-constrained portable electronics.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable computing devices requiring multiple low-voltage rails

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix code against official datasheets to confirm output voltage configurations, as variations exist within the family. Ensure compatibility with the intended thermal management solution given the WFBGA package type. Confirm RoHS compliance status through manufacturer documentation before integration into regulated assemblies.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when dual isolated outputs are required from a single high-efficiency regulator topology. The integrated dynamic voltage scaling makes it suitable for applications demanding variable load performance. Compare against standard buck regulators if only a single output rail is necessary to optimize board space and cost.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3370 series of dual synchronous step-down converters. It shares architectural similarities with other members like the LM3370SD variants but differs in package style and specific factory-set output voltages. The series targets portable applications needing efficient power conversion from single-cell sources.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM3370SD-3416/NOPB and LM3370SDX-4221/NOPB, though pinout and package differences require careful mechanical review. Verify equivalent electrical specifications before cross-referencing with non-TI alternatives.
