Product Details

Demonstration circuit 2270A is a dual-channel low noise bias generator featuring LT3095. The LT3095 generates two low noise bias supplies from a common input voltage range from 3V to 20V. Each channel includes a fixed frequency, peak current mode step-up switching regulator and a low noise, single resistor programmable linear regulator. The maximum load current is 50mA for each channel, and the two output voltages are 5V and 15V.

Each boost regulator adjusts its output voltage to 2V above the corresponding linear regulator’s output voltage, optimizing power dissipation, PSRR and transient response.
