The SGM62180 is a two-phase, synchronous step-down DC/DC converter with integrated power MOSFETs. Using two identical current balanced phases with peak current mode control, the SGM62180 is a perfect low profile solution for height restricted applications. The step-down converters operate with phase delay to minimize the required input capacitance and reduce the EMI generation.
With a wide input voltage range of 4V to 15V and a very low quiescent current of 28μA, the SGM62180 is well suited for systems powered by multi-cell Li-Ion batteries, particularly for 12V applications. It can deliver 6A continues current which is equally shared between the phases. Dividing current between two phases allows the use of thinner inductors required for low profile
The efficiency is automatically maximized in the full duty cycle range by adjusting the switching frequency to the optimal value depending on VIN and VOUT voltages. The loss is also minimized at very light loads by the automatic activation of the power-save mode (PSM).
Other features include adjustable soft-start time, tracking, and power good output signal. The SGM62180 can operate with 100% duty cycle for very low dropout. It is also capable to work at high step-down ratios without duty cycle limitation.
The SGM62180 is available in a tiny 24-bump Green WLCSP package with 0.5mm pin pitch. It operates over an ambient temperature range of -40℃ to +125℃.
