The SGM61169 is an efficient 6A synchronous Buck converter with a wide 4V to 18V input voltage range and an internally compensated innovative emulated current mode (IECM) control with fixed frequency. The device has 5 fixed selectable switching frequencies, from 500kHz to 2.2MHz, which can be used to provide high efficiency and external clock synchronization with the SYNC/FSEL pin. It also has the features like selectable soft-start times, selectable current limits, monotonic startup and power good output monitor.
The SGM61169 also provides full protections, including over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), and thermal shutdown.
The SGM61169 is available in a Green TQFN-3× 2.5-14L package.
