LTC3260 Inverting Charge Pump Converters

Analog Devices Inc. LTC3260 Dual-Supply Inverting Charge Pump Converters are low-noise, DC/DC converters with dual polarity output power supplies. The LTC3260 features both positive and negative low dropout (LDO) regulators that can source up to a 50mA output current each. This design allows the LTC3260 to deliver up to 100mA output over a 4.5V to 32V input voltage range. Designers can use the external resistor dividers to adjust the positive and negative LDO output voltages down to 1.2V and -1.2V, respectively.
