The SGM64104 is a voltage-mode controlled Buck controller with an operating voltage range of 4.5V to 18V. The operating frequency of SGM64104A is fixed at 600kHz and the SGM64104B is fixed at 300kHz. Smaller inductors and output capacitors can be used for higher frequency, making the layout more compact and cost-optimized. 

The device senses the voltage difference between SW and GND and compares it with the selected current limit threshold to perform low-side valley current limit protection. Users can select three different current limit threshold voltages of 100mV, 200mV and 280mV by connecting an external resistor (RCOMP) between COMP and GND. This current limit threshold is latched during startup. And the high-side over-current protection is achieved by comparing the sensed voltage difference between VDD and SW with an internal 550mV threshold voltage, and the high-side MOSFET will be shut off immediately. When the device determines an output short-circuit, both high-side and low-side MOSFETs are turned off, and the device attempts to restart after hiccup timeout. 

The SGM64104 is available in a Green TQFN-3×3-10L package and can operate in the -40℃ to +125℃ temperature range.
