(1)
Under a balanced load, current flowing out of VO1 is equal to that flowing into VO2.
(2)
SOA curves represent the conditions at which internal components are at or below the manufacturer's maximum operating
temperatures. Derating limits apply to modules soldered directly to a 4 in.
× 4 in. double-sided PCB with 1 oz. copper.
