SGM66055A 2.2MHz, Fixed Output Synchronous Tiny Boost Converter with a 3A Switch

2022-01-15
●GENERAL DESCRIPTION:
■The SGM66055A is an internally compensated, 2.2MHz switching frequency, current mode, synchronous boost 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, the output voltage follows the input voltage with a voltage drop by the resistance of the inductor and high-side MOSFET.
■The SGM66055A-5.0 and SGM66055A-5.4 are preset for outputting 5.0V and 5.4V.
■The device is available in a Green WLCSP-1.21×1.21-9B package and operates over an ambient temperature range of -40°C to +85°C.
●FEATURES:
■Operating Input Voltage Range: 2.5V to 4.5V
