SGM66052 Efficient Synchronous Boost Converter with a 2.7A Switch
●The SGM66052 is an internally compensated, 1.1MHz switching frequency, current mode, synchronous Boost switching regulator, which is capable of generating 5V output at 1A load current from a 3.3V rail. This device also has the 5.1V fixed output version.
●This device turns into power-saving mode to maintain high efficiency by lowering switching frequency. With its anti-ringing circuitry damping the charge in parasitic capacitor, it reduces EMI interference significantly. Its output is disconnected by the rectifier circuit during shutdown, with no input to output leakage.
●The SGM66052-5.1 is preset for outputting 5.1V, while the SGM66052-ADJ is output voltage programmable with an external resistor divider.
●The device is available in a Green UTDFN-2×1.5-6L package and operates over an ambient temperature range of -40°C to +85°C.
■FEATURES:
●2.2V to 5.1V Input Voltage Range
●5.1V Fixed Output Voltage
●6V Output Voltage Clamping
●Adjustable Output Voltage up to 5.1V
●Up to 90% Efficiency
●20μA (TYP) Device Quiescent Current
●1μA (MAX) Shutdown Current
●Improved Light Load Efficiency with Power-Save Mode (PSM)
●Load Disconnect during Shutdown
●Low Reverse Leakage Current when VOUT > VIN
●Over-Temperature Protection
●Available in a Green UTDFN-2×1.5-6L Package
●-40°C to +85°C Operating Temperature Range
