LM2662M/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2662M/NOPB is a switched capacitor voltage converter manufactured by Texas Instruments, housed in an SOIC-8 package. It accepts input voltages from 1.5 V to 5.5 V and provides negative output voltages ranging from -1.5 V to -5.5 V with a maximum output current of 200 mA. The device operates at selectable oscillator frequencies of 20 kHz or 150 kHz, controlled via the FC pin. Quiescent current is typically 300 µA, dropping to 10 µA in shutdown mode. It functions as both an inverter and a positive voltage doubler.
