LTC3261MPMSE#PBF

Voltage Regulators - DC DC Switching Regulators Overview

The LTC3261MPMSE#PBF is a high-voltage, low-noise dual charge pump regulator designed for demanding power management applications. It integrates two independent charge pumps capable of generating positive and negative output voltages from a single input supply. The device supports an input voltage range of 4.5 V to 32 V, with maximum output capabilities reaching 32 V. Each channel provides up to 100 mA of output current. Operating at a switching frequency between 50 kHz and 500 kHz, the IC ensures efficient energy transfer while maintaining low quiescent current consumption. The component is housed in a thermally enhanced 16-lead MSOP package, suitable for surface-mount assembly.
