Measuring 9 mm2 , the four-channel MAX8667/MAX8668 PMICs integrate two step-down dc/dc converters and two dropout regulators, as well as all feedback networks. The TQFN-packaged chips also feature 1.5-MHz switching frequency, 93% efficiency, and a quiescent current of 100 µA typ with all regulators enabled.
One of the dc/dc converters delivers up to 1.2-A output current, while the other delivers up to 600 mA. The LDOs operate down to 1.7 V, while the output voltages of the dc/dc converters are adjustable from 0.6 to 3.3 V (MAX8668) or factory preset (MAX8667). (From $2.95 ea/2,500available now.)
