说明

AW37418/9 series are 6MHz DC-DC step-down converters with extremely small package. The AW37418 works in three operation modes. At heavy load, the device operates in 6MHz fixed frequency PWM mode. At light load, the AW37418 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 45μA for the purpose to extend the battery life. The AW37419A works in forced PWM mode which can achieve extremely low output ripple throughout the load. The device is off in Shutdown mode and reduces the supply current to 0.1μA(typical). AW37418/9 series are available in WLCSP-5B 0.968mm × 0.888mm -5B Packages. The high switching frequency 6MHz allows the use of the economic size-saving external components, two ceramic capacitors and one 0.47μH inductor are required.
