Application Example

Start-up Settings

Case 1) Standalone or master chip in parallel operation

With the RC network on the TRK-SS pin, the voltage on the pin should ramp up slowly.

0.6 V

TSS = − CR × Ln (1 − 0.6 V / 5 V) (s)

ON/OFF

TRK-SS

Vout

Case 2) Coincident tracking

The TRS-SS signal for channel two is the voltage from Vout1 after division by a resistor network. Vout1

must be greater than Vout2. Cross-talk is not generated between the channels.
