The SGM64620 is a 65V dual-channel synchronous Buck controller using peak current mode control, which can provide 3.3V or 5V fixed output voltage or adjustable 0.6V to 55V voltage range. It is capable to drive external N-MOSFETs over the whole voltage range.
The device has optional hiccup mode or cycle-by-cycle current limiting in PWM mode. Power-save mode (PSM) is optional at light load to improve efficiency. Optional spread spectrum frequency modulation (SSFM) is provided to optimize the EMI.
Switching frequency can be programmed by external resistor or synchronized to an external clock. 180° interleaved clock is provided for two channels to reduce the input current ripple. Other functions such as adjustable soft-start time, SYNCOUT signal, open-drain power-good indication (PG), UVLO protection, over-voltage protection (OVP), current limit protection (OCP) and thermal shutdown are included in the SGM64620.
The SGM64620 is available in a Green TQFN-6×6-40EL package.
