    20V Output Voltage Step-Up Converter
    20V Output Voltage Step-Up Converter

    The SGM6602 is a highly integrated boost converter designed for applications requiring high voltage and tiny solution size such as PMOLED panel and sensor module. The SGM6602 integrates a 20V power switch, and an input/output isolation switch. It can output up to 20V from input of a Li+ battery or two cell alkaline batteries in series.

    The SGM6602 operates with a switching frequency at 1.1MHz. This allows the use of small external components. The SGM6602 has an internal default 9V or 12V output voltage setting by connecting the FB pin to the VIN pin. Thus it only needs three external components to get 9V or 12V output voltage. Together with CSP package, the SGM6602 gives a very small overall solution size. The SGM6602 has typical 900mA switch current limit. It has 5ms built-in soft-start time to minimize the inrush current. When the SGM6602 is in shutdown mode, the isolation switch disconnects the output from input to minimize the leakage current. The SGM6602 also implements output short-circuit protection, output over-voltage protection and thermal shutdown.

    The SGM6602 is available in Green WLCSP-0.8×1.2-6B and TDFN-2×2-6L packages. It operates over an ambient temperature range of -40 to +85.
