The SGM6604 is a fully integrated synchronous Boost converter which integrates a 20V main power switch and an input/output isolation switch. The isolation switch provides true load disconnection when SGM6604 is in shutdown mode. The SGM6604 is capable to start up from 1.85V input, which is suitable for single-cell Li-Ion battery or two-cell alkaline batteries in series. The device can provide up to 20V output voltage which makes it an excellent choice for PMOLED panel bias and applications requiring high voltage in a small solution size.
The SGM6604 has an internal fixed 12V output voltage setting by connecting the FB pin to the VIN pin. Thus, it only needs three external components to achieve 12V output voltage. The SGM6604 has 1.12A typical switch current limit and 6ms built-in soft-start time to minimize the inrush current. When the SGM6604 is disabled via EN pin, the isolation switch disconnects the output from input to minimize the leakage current. The SGM6604 also implements various protection features such as output short-circuit protection, output over-voltage protection and thermal shutdown.
The SGM6604 is available in a Green SOT-23-6 package. It operates over an ambient temperature range of -40℃ to +85℃.
