LM3206TL/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM3206TL/NOPB is a miniature step-down DC-DC converter designed for portable applications, optimized to power devices from a single Lithium-Ion cell. It accepts an input voltage range of 3.25V to 5.5V and provides a fixed output voltage of 3.09V. The device features a typical PWM switching frequency of 2 MHz, enabling the use of small surface-mount components. It delivers a maximum load capability of 650mA with high efficiency, reaching up to 96% at 3.6V input and 400mA load. The converter operates in an 8-pin lead-free micro SMD package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific part number includes the NOPB suffix to confirm lead-free compliance and RoHS status as documented by Texas Instruments. Confirm the package type matches the required 8-pin micro SMD footprint for PCB layout compatibility. Ensure the design supports the fixed 3.09V output requirement, as this variant does not offer adjustable output options.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.09V output is required from a single-cell Lithium-Ion source. The 2 MHz switching frequency allows for smaller external inductors and capacitors compared to lower-frequency converters. Consider the 650mA current limit and ensure it meets the system's peak load requirements without triggering current overload protection.
