AW37426LGR

AW37426 is a 6MHz DC-DC step-down converter suitable for RF power amplifiers supplied by a single battery. The device provides a regulated adjustable output voltage from 0.5V to 3.4V, 2.2V to

5V input voltage range. The AW37426 works in three operation modes. At heavy load, the device operates in 6MHz fixed frequency PWM mode to minimize the RF interference. At light load, the AW37426 enters peak-current-control PFM mode automatically to reduce the switching losses. In PFM mode, the quiescent current consumed by the part is reduced to 27μA for the purpose to extend the battery life.

The device is off in Shutdown mode and reduces the supply current to 0.1μA(typical). AW37426 is available in a LGA 2.48mm X 1.77mm X 0.54mm-24L Package. The high switching frequency 6MHz allows the use of the economic size-saving external components, two ceramic capacitors and one 1μH inductor are required.
