Function

TTL-Level Input Signal. Has primary control of the drive outputs.

Shutdown. When high, this pin enables normal operation. When low, DRVH and DRVL are forced low

and the supply current (ICCQ) is minimized as specified.

Drive-Low Shutdown. When DRVLSD is low, DRVL is kept low. When DRVLSD is high, DRVL is

enabled and controlled by IN and by the adaptive OPC function.

High-Side Turn-On Delay. A resistor from this pin to ground programs an extended delay from turn-off

of the lower FET to turn-on of the upper FET.

Input Supply. This pin should be bypassed to GND with a ~10 mF ceramic capacitor.

Synchronous Rectifier Drive. Output drive for the lower (synchronous rectifier) FET.

Ground. Should be directly connected to the ground plane, close to the source of the lower FET.

This pin should be connected to the buck switching node, close to the upper FET’s source. It is the

floating return for the upper FET drive signal. Also, it is used to monitor the switched voltage for the

OPC function.

Buck Drive. Output drive for the upper (buck) FET.

Floating Bootstrap Supply for the Upper FET. A capacitor connected between BST and SW pins holds

this bootstrapped supply voltage for the high-side FET driver as it is switched. The capacitor should be a

MLC type and should have substantially greater capacitance (e.g., ~ 20ϫ) than the input capacitance of

the upper FET.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection. Although

the ADP3415 features proprietary ESD protection circuitry, permanent damage may occur on

devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are

recommended to avoid performance degradation or loss of functionality.
