Low IQ Synchronous Boost, ET820982, ETEK Microelectronics
The ET820982 is a low power synchronous boost converter. It integrates a Low-dropout Linear Regulator (LDO) with a boost converter and provides two output rails. The boost output VMAIN is designed as an always-on supply for a main system, and the LDO output VSUB is designed as an always-on supply for power peripheral devices. The ET820982 supports automatic pass-through function. When input voltage is higher than pass-through threshold, the boost converter stops switching and passes the input voltage to the VMAIN rail; when input voltage is lower than the threshold, the boost works in Boost mode and regulates the output at the target value. The ET820982 can provide up to 50mA total output current at 0.7V input to 3.3V output conversion and with maximum efficiency at minimal quiescent current.
