3 / 16 page Pin Description Pin Name Function 1-2 SW Switched-node connection, which is connected to the source of the internal high-side MOSFET. 3-5 PV IN Main power supply input pin. Connected to the drain of the internal high-side MOSFET. 6V CB Bootstrap capacitor connection for high-side gate drive. 7AV IN Input voltage for control and drive circuits. 8 SD(SS) Shutdown and Soft-start control pin. Pulling this pin below 0.3V shuts off the regulator. A capacitor connected from this pin to ground provides a control ramp of the input current. Do not drive this pin with an external source or erroneous operation may result. 9 FB Output voltage feedback input. Connected to the output voltage. 10 COMP Compensation network connection. Connected to the output of the voltage error amplifier. 11 L DELAY A capacitor between this pin to ground sets the delay from when the output voltage reaches 80% of its nominal to when the undervoltage latch protection is enabled. 12 LDR Low-side FET gate drive pin. 13 GND Power ground. 14-16 PV IN Main power supply input pin. Connected to the drain of the internal high-side MOSFET. Ordering Information Supplied as 1000 units Tape and Reel Supplied as 3000 units, Tape and Reel LM2655MTC-3.3 LM2655MTCX-3.3 LM2655MTC-ADJ LM2655MTCX-ADJ www.national.com 3 |
