ETA1067
ETA1067 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 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 ofthe boost enable control, the LDO 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 ETA1067 is available in a QFN2x2-8L package
