钰泰半导体 ETA1066D2I 双通道迷你PMU芯片

　　DESCRIPTION

　　ETA1066 is a two-channel PMU that includes a 12V high efficiency step-up converter and an 12V LDO. The boost converter is capable of providing up to 12V output with 2.2A input current from a single cell of two-cell series Li-ion battery. Once it's started up, the internal circuitry is powered from the LDO output. Therefore, even when the input voltage drops to a very low level, the output still maintains stable regulation down to 0.5V input. The LDO is powered from an independent pin LDOIN and is capable of delivering up to 150mA output current. Independent of the boost enable control, the LD0 is still operates even when the boost is turned off, as the power comes from input through the external Schottky diode.

　　With all the features, the ETA1066 is available in a QFN2x2-8L package
