SGM66051
Efficient Synchronous Boost Converter with a 2.7A Switch
3.5A Valley Current, 0.5V Ultra-Low Input, Synchronous Boost Converter
The SGM66051 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 SGM66051-5.1 is preset for outputting 5.1V, while the SGM66051-ADJ is output voltage programmable with an external resistor divider.
The device is available in a Green TSOT-23-6 package and operates over an ambient temperature range of -40℃ to +85℃.
