A new triple-output stepdown switching regulator IC, featuring three high-current outputs that are adjustable from 0.8 V to 5 V with a maximum current of 2 amps, has been introduced by Allegro Microsystems. Operating from an input voltage of 4.5 V to 34 V, the A4490 uses multiphase switching to reduce EMI and to minimize stress on the input capacitors by interleaving the turn-on cycle of the regulators. The device features soft start, power-on reset output, and a small 4-x-4 mm QFN package making it a suitable choice for many portable, office automation, and consumer products. The A4490 uses 550-kHz fixed frequency switching, which allows the selection of small, inexpensive inductors and ceramic output capacitors. A charge pump is used to provide the supply driving the power switches’thus ensuring operation at very wide operating duty cycles and avoiding the need for power-draining clamp circuits.
