CM8562A

ABSOLUTE MAXIMUM RATINGS

Absolute maximum ratings are those values beyond which the device could be permanently damaged.

VIN, VCCA, VFB …................................…....……………..7V

Storage Temperature ……................……. -65°C to 125°C

Output RMS Current, Source or Sink .....…………........…...2A

Lead Temperature (Soldering, 5 sec)………….…….. 260°C

VIN=+2.5V and VCCA=+3.3V, VREFEN=1.25V)

maximum ratings are stress ratings only and functional device operation is not

implied. (Note 1)

Note 1:

Limits are guaranteed by 100% testing, sampling, or correlation with worst case test conditions

Note 2:

VOS = VREFEN – VOUT

Note 3:

Keep VCCA >= VIN and VCCA >=VREFEN + 1.9V on operation power on and power off sequences

Note 4:

Guaranteed by design, not 100% test
