Description

The GigaTLynx

regulated output voltage from 0.7Vdc to 2.0Vdc, programmable via an external resistor. Features include remote

On/Off, adjustable output voltage, over current and over temperature protection, output voltage sequencing and

paralleling. A new feature, the Tunable Loop

to match the load with reduced amount of output capacitance leading to savings on cost and PWB area.
