LM2776DBVT TI DC-DC Converter | SOT-23-6 | -2V to -5.5V, 200mA

Product Overview

The LM2776DBVT is a high-performance switched capacitor voltage inverter from Texas Instruments, designed to generate a regulated negative output voltage from a positive input voltage. Housed in a compact SOT-23-6 package, this device delivers up to 200mA output current with minimal external components, making it ideal for space-constrained applications. The LM2776 operates over a wide input voltage range of 2.7V to 5.5V and provides a programmable output voltage from -2V to -5.5V. Its high switching frequency of 2MHz allows for small external capacitors, reducing board space and bill of materials.
