The SGM61042 is a high power density synchronous Buck converter, which is capable of delivering up to 4A continuous output current from 2.4V to 5.5V input voltage range. The device only consumes 5μA (TYP) quiescent current.
The device implements auto PFM mode operation to maximize the efficiency at light load condition. At moderate to heavy load, the device automatically switches to CCM operation with a 2.2MHz (TYP) switching frequency. Forced PWM (FPWM) is also available via the VSET/MODE pin for low output voltage ripple requirement.
The SGM61042 implements the COT control architecture that incorporates the benefits of fast load and line transient responses and low output voltage ripple, which is beneficial for RF and noise sensitive applications. The device features the hiccup short-circuit protection and thermal shutdown.
The SGM61042 is available in a Green TQFN-1.5×2.5- 9L package.
