Charge pump solutions are often thought to be too noisy for low noise applications. Engineers associate charge pump power supplies with peak-to-peak noise levels in the 20mV to 200mV range. Linear Technology's latest family of regulated charge pump plus linear regulator power supply solutions are inductorless, small size, low ...

High Voltage Inverting Charge Pump Produces Low Noise Positive and Negative Supplies

Martin Merchant - Sr. Applications Engineer Oct 1st 2012
Introduction Dual-polarity supplies are commonly needed to operate electronics such as op amps, drivers, or sensors, but there is rarely a dual-polarity supply available at the point of load. The LTC®3260 is an inverting charge pump (inductorless) DC/DC converter with dual low noise LDO regulators that can produce positive ...
