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
●ESD sensitive device, take proper precaution while handling the device.
