MCP1252-ADJI/MS

The MCP1252-ADJI/MS is an inductor less positive regulating low noise charge pump DC-to-DC Converter with an adjustable output between 1.5 and 5.5V. Both can deliver 120mA of load current at the selected regulated output voltage. Since the device incorporates an automatic buck/boost feature, it will maintain the regulated output voltage whether the input voltage is above or below the output voltage. These charge pumps operate at a switching frequency of 650kHz and feature power saving shutdown pins, short-circuit protection, thermal shutdown, and power-good pins that report out-of-regulation conditions.

• Supplies regulated output voltages for up to 120mA loads
• Low 60µA supply current in no load conditions
• High 2.5% voltage accuracy (on fixed voltage outputs)
• High 650kHz operation to avoid interference with IF bands
• Logic level shutdown control reduces current consumption to 0.1µA during standby operation
• Power-Good output indicator with hysteresis
• Thermal shutdown protection with hysteresis
• Short-circuit protection
• Soft-start circuitry to minimize inrush current
