from the discussion above, p d(max) was determined to equal 500mw at t a = 25c. thus, the aat3220 can sustain a constant 3.0v output at a 150ma load current as long as v in is 6.33v at an ambient temperature of 25c. 5.5v is the maximum input operating voltage for the aat3220, thus at 25c, the device would not have any thermal concerns or operational v in(max) limits. this situation can be different at 85c. the following is an example for an aat3220 set for a 3.0v output at 85c: ! "#$ % &' ( % )*+ , &'( = 150ma i gnd = 1.1a v in(max) = 4.33v 200mw + (3.0v ? 150ma) 150ma + 1.1a from the discussion above, p d(max) was determined to equal 200mw at t a = 85c. higher input-to-output voltage differentials can be obtained with the aat3220 while maintaining device functions in the thermal safe operating area. to accom - plish this, the device thermal resistance must be reduced by increasing the heat sink area or by operating the ldo regulator in a duty-cycled mode. for example, an application requires v in = 5.0v while v out = 3.0v at a 150ma load and t a = 85c. v in is great - er than 4.33v, which is the maximum safe continuous input level for v out = 3.0v at 150ma for t a = 85c. to maintain this high input voltage and output current level, the ldo regulator must be operated in a duty-cycled mode. refer to the following calculation for duty-cycle operation: - . / 0 1 23 4 0 5 65 7 8 1 9: ; = 150ma v in = 5.0v v out = 3.0v %dc = 66.67% p d(max) (v in - v out ) ? i out + (v in ? i gnd ) %dc = 200m (5.0v - 3.0v) ? 150ma + (5.0v ? 1.1a) p d(max) is assumed to be 200mw. for a 150ma output current and a 2.0v drop across the aat3220 at an ambient temperature of 85c, the maxi - mum on-time duty cycle for the device would be 66.67%. downloaded from: http:///
