SGM66055B 2.2MHz, Fixed Output Synchronous Tiny Boost Converter with a 2.4A Switch
■The SGM66055B is an internally compensated, 2.2MHz switching frequency, current mode, synchronous Boost switching converter. The SGM66055B supports up to 800mA load current from a battery as low as 2.65V, and the output voltage is fixed at 5.0V. This device turns into power-save mode to maintain high efficiency at light load currents. Its output is disconnected by the rectifier circuit during shutdown with no input to output leakage.
■The SGM66055B has built-in protection features such as short-circuit protection, over-current protection and thermal shutdown.
■The SGM66055B is available in a Green WLCSP-1.21×1.21-9B package.
●FEATURES
