The SGM660 is a synchronous inverting Buck-Boost converter. The device implements a multi-function digital input SWIRE pin which can be used to program the negative output voltage or device enable.
The SGM660 integrates a 810mA switch current power FET, which can be programmable down to 435mA. 1.8MHz switching frequency allows the use of small size inductor. The device has built-in soft-start and loop compensation network to reduce the external component counts. Output discharge function is also implemented.
Various protection features such as over-current protection, over-temperature protection and short circuit protection are implemented to protect the device against various fault conditions.
The SGM660 is available in a Green WLCSP-0.9×1.3-6B package.
