SGM66052 Efficient Synchronous Step-Up Converter
with a 2.7A Switch in UTDFN Package
GENERAL DESCRIPTION
The SGM66052 is an internally compensated, 1.1MHz switching frequency, current mode, synchronous stepup switching regulator, which is capable of generating 5V output at 1A load current from a 3.3V rail.
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.
