DESCRIPTION
The SGM63600Q is a 4V to 60V current mode controller for synchronous Buck converters. It is capable to efficiently drive two N-MOSFETs over the whole voltage range.
This device uses accurate cycle-by-cycle current limiting in PWM operation. Power-save mode (PSM) is used at light load to keep high efficiency. It can also enter non-synchronous PWM mode if the PSM is enabled.
Switching frequency can be set by an external resistor (RFREQ), or an external clock (SYNC input) for low noise applications. The protection functions include UVLO, thermal shutdown, accurate output over-voltage protection (OVP) and over-current protection (OCP).
The device is AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and it is suitable for automotive applications.
The SGM63600Q is available in a Green TQFN-3×4-20AL package.
