MCP1253-ADJI/MS Datasheet PDF - Microchip

●The MCP1253-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 1MHz (reducing capacitor sizes) 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 1MHz operation to avoid interference with IF bands

● Logic level shutdown control reduces current consumption to 0.1µA during standby operation

● Allows for small capacitor use to save board space and cost

● 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.
