Datasheet Summary
SGM660 Buck-Boost Converter for
Negative Output Voltage
GENERAL DESCRIPTION
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 pensation network to reduce the external ponent counts. Output discharge function is also implemented.
Various protection Features such as over-current protection, over-temperature protection and short circuit...
