16V/12A, Synchronous Buck Converter with Adjustable Current Limit, Selectable Frequency, and Voltage Tracking

SGM611A13.pdf

The SGM611A13 is a high-efficiency high-frequency synchronous Buck DC/DC converter with a wide input voltage range of 4.5V to 16V and a wide output current range, optimized for compact solutions. With an internally compensated constant on-time (COT) control mode architecture, ultra-fast dynamic response is achieved, and loop stabilization is guaranteed with ease.

The switching frequency of the converter can be set to 600kHz, 800kHz or 1000kHz with a MODE pin, which allows the converter frequency to stay at a fixed value independent of the input and output voltages.

The SGM611A13 has voltage tracking capability in which output voltage can track the voltage applied at the TRK/REF pin. A ceramic capacitor, which determines the soft-start time, should be placed as close to TRK/REF pin as possible.

The power-good (PGOOD pin) is an open-drain output that is provided to signal the status of the output voltage to the downstream system. When the input supply is unable to power the device, the V_PG can be clamped low by itself with external pull-up resistor.

The device integrates various protection features such as over-voltage protection, over-current protection, input under-voltage lockout and thermal shutdown. In addition, the synchronous rectifier supports short circuit protection which further improves the robustness of the device.

The SGM611A13 is available in a Green TQFN-3×4-21L package.
