Housed in 7 x 7 mm, 48-lead LFCSP package, ADP505x Series combines 4 buck switching regulators (4 A, 4 A, 1.2 A, and 1.2 A) with one 200 mA low dropout regulator, providing power density of 25 W in 310 mm² PCB area. All 4 switching regulators operate over wide input voltage range of 4.5–15 V and are synchronized to single clock with programmable range of 250 kHz to 1.4 MHz. Programmable phase shifts of 0°, 90°, 180°, 270° on each buck regulator minimize input ripple.
