LTC3245 Inductorless Charge Pump DC/DC Converters

Analog Devices Inc. LTC3245 Inductorless Charge Pump Converters are buck-boost DC/DC converters that generate 3.3V, 5V, or adjustable output from a 2.7V to 3V input voltage. The converter's internal circuitry selects the conversion ratio automatically to maximize efficiency as input voltage and load conditions change. To further optimize efficiency, designers can operate the converters in pin selectable burst mode. The constant-frequency architecture enables the Analog Devices Inc. LTC3245 converters to offer a lower noise output than conventional charge pump regulators. With an operating current as low at 20µA, the LTC3245 converters are well-suited for low-power, space-constrained automotive and industrial applications.
