Ratio(5)

RA

VCTRL = VIN = 5V, IOUT = 5A

80dB 60dB (Min)

NOTE :

(1) Low duty cycle pulse testing with Kelvin connections required.

(2) Minimum input to output voltage differential required to maintain 1% regulation.

(3) Current used to drive the output section.

(4) Required to maintain regulation. Resistor divider R1, R2 is usually utilized for minimum load current.

(5) VRIPPLE = 1VPK-PK, 120Hz.

(6) 30ms.
