Datasheet Summary
SGM66055A 2.2MHz, Fixed Output Synchronous Tiny Step-Up Converter with a 3A Switch
GENERAL DESCRIPTION
The SGM66055A is an internally pensated, 2.2MHz switching frequency, current mode, synchronous stepup switching regulator. Even below the minimum system battery voltage, the device maintains the output voltage regulation for a minimum output load current of 0.7A. This device turns into power-save 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.
In addition, the SGM66055A device can also support the pass-through mode by pulling EN to low. In this mode,...
