DC ELECTRICAL CHARACTERISTICS

AGND = DGND = PGND = 0 V; All voltages with respect to ground; PWM switch rate = 384 kHz; Unless otherwise

specified.

Notes:

14. Normal operation is defined as RST = HI.

15. Power-Down Mode is defined as RST = LOW with all input lines held static.

16. The DC current drain represents the allowed current from the VQ pin due to typical leakage through

the electrolytic de-coupling capacitors.

17. Valid with the recommended capacitor values on FILT+ and VQ. Increasing the capacitance will in-

crease the PSRR.
