The SGM61114 is a high frequency synchronous Buck converter optimized for simple and quick application to high density designs. High output voltage accuracy and fast transient response along with small LC output filter elements are easily achievable with the pin selectable switching frequency and the AHP-COT control.
The 3V to 17V input voltage range makes this device a suitable choice for both 12V input power rails and the battery powered applications including Li-Ion batteries. It supports 100% duty cycle operation and can provide 1A continuous current to its adjustable or fixed output voltage versions. The SGM61114 can operate as a standalone power supply with adjustable soft-start ramp or as a tracking power supply using the SS/TR input pin. The enable input (EN) and power-good output (PG) pins provide power sequencing capability.
In power-save mode (PSM), the VIN quiescent current is reduced to 32μA (TYP). Operation mode is seamlessly changed between PWM and PSM to keep the efficiency high in entire load range. Mode changing is automatically decided based on the load current at the DCM/CCM changeover level.
In the shutdown mode, the device is completely turned off and the current consumption drops to 3μA typically.
The SGM61114 is available in a Green TQFN-3×3-16L package.
