Description

The Pico TLynx

output voltage from 0.6Vdc to 3.63Vdc, programmable via an external resistor. Features include remote On/Off,

adjustable output voltage, over current and overtemperature protection, and output voltage sequencing (APTH

versions). A new feature, the Tunable Loop

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