LM2663M/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2663M/NOPB is a switched capacitor voltage converter manufactured by Texas Instruments, housed in an 8-SOIC package. It operates with an input voltage range of 1.5 V to 5.5 V and delivers a maximum output current of 200 mA. The device supports ratiometric output configurations, providing fixed outputs of -Vin, 2Vin, or Vin/2. It functions as a charge pump regulator with a switching frequency up to 150 kHz and operates within a temperature range of -40 °C to 85 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Provides ratiometric voltage conversion capabilities for generating inverted, doubled, or halved supply rails from a single input source.
• Integrates internal switching elements and control circuitry into a compact surface-mount package for simplified design.
• Supports positive or negative output configurations suitable for diverse power management requirements.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable devices requiring dual polarity supplies from a single battery source
• RS-232 interface circuits needing voltage inversion
• LCD bias voltage generation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free construction compliant with RoHS standards. Confirm the package marking matches the 8-SOIC physical dimensions. Ensure the operating environment stays within the specified -40 °C to 85 °C thermal limits. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a ratiometric charge pump solution is required for low-power applications. It is suitable for designs needing -Vin, +2Vin, or +Vin/2 outputs without external inductors. Consider the 200 mA current limit and 1.5 V minimum input voltage when sizing the power supply. Evaluate the 8-SOIC footprint against available PCB space constraints.

Voltage Regulators - DC DC Switching Regulators Part Context
