- RTN Signal RTN referenced to VIN Signals Description– Type 1 INHIBIT Description: Inhibits all outputs Use: Apply short circuit or TTL "LOW" to inhibit all outputs Leave open or apply TTL "HIGH" to enable all outputs Referenced to: SIGNAL RTN SYNC .Description: Synchronizes internal switching frequency to system clock Use: Apply TTL level, 250kHz ± 10kHz, 50% duty-cycle clock Leave open if unused. In this case, the switching frequency will be set by the internal clock (~250KHz) Referenced to: SIGNAL RTN SENSE 1 & SENSE 1 RTN Description: Used to achieve accurate voltage regulation for output 1 at load terminal, to dcompensate for voltage drop across the leads connecting the converter to the loa 5V2Limited to 0. Use: Connect SENSE line directly to the load's positive terminal, and SENSE RTN directly to the load's negative terminal If not used, connect SENSE 1 to OUT 1 and SENSE 1 RTN to OUT 1 RTN. Do not leave open

Special Signals Description - Type 2 INHIBIT 1 Description: Inhibits OUT 1. Use: Apply input voltage between INHIBIT 1 and SIGNAL RTN pins to inhibit selected output. Leave open or short INHIBIT 1 and SIGNAL RTN pins to enable output. Referenced to: SIGNAL RTN INHIBIT 2 Description: Inhibits OUT 2. Use: Apply input voltage between INHIBIT 2 and SIGNAL RTN pins to inhibit selected output. Leave open or short INHIBIT 2 and SIGNAL RTN pins to enable output. Referenced to: SIGNAL RTN SIGNAL RTN Description: Reference for INHIBIT 1 and INHIBIT 2 signals. Use: Apply signal between desired pin and this pin to initiate desired action. Referenced to: This signal is isolated from all rails and returns in the power supply.
