Up to 60V Input, Current Mode Synchronous Buck Controller, REPLACE MP9928
The SGM63600 is a 4.3V 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 SGM63600 is available in Green TQFN-3×4-20L and TSSOP-20 (Exposed Pad) packages. It can operate in the -40℃ to +125℃ junction temperature range.
