Microchip Charge Pump DC/DC Converter 120mA 3.3V MSOP-8 SMD

Microchip Charge Pump 120mA delivers a regulated 3.3V fixed output, or an adjustable voltage, from a 2V to 5.5V input with up to 120mA output current.

Overview

This inductorless, positive-regulated charge pump DC/DC converter is engineered for high efficiency and low-noise operation. Its design allows the input voltage to be either lower or higher than the output voltage by switching automatically between buck and boost modes, supporting diverse power management needs.

The device operates at a switching frequency of 650kHz, which helps avoid interference with intermediate frequency (IF) bands, making it suitable for sensitive electronic applications.

Key Features

• Short-circuit protection, thermal shutdown with hysteresis, and soft-start circuitry to minimise inrush current during power-up
• Logic-level shutdown control to reduce standby current to 0.1µA
• Power-good output indicator that reports out-of-regulation conditions
• Low 60µA no-load supply current
• Voltage accuracy of 2.5% on fixed outputs

Handling

This is an ESD-sensitive device, so proper ESD handling precautions should be observed during use.
