Description

The 12V TLynx

regulated output voltage from 0.69Vdc to 5.5Vdc, programmable via an external resistor. Features include

frequency synchronization, remote On/Off, adjustable output voltage, over current and temperature protection,

power good and output voltage sequencing. The Ruggedized version (-D) is capable of operation up to 105°C and

withstand high levels of shock and vibration. The Tunable Loop

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

area.

RoHS Compliant
