The SGM61162 is an adaptive constant on-time control (ACOT) synchronous Buck converter with a wide input voltage range of 4.5V to 18V. This device has 6A output current capability and operates at pseudo-fixed frequency. It is an easy-to-use device with power switches and internal compensation circuit, which are all integrated in a small 6-pin package, and supports low equivalent series resistance (ESR) output capacitors. A typical 2ms soft-start ramp is also included to minimize the inrush current.
Protection features include cycle-by-cycle current limit, hiccup mode short-circuit protection and thermal shutdown in case of excessive power dissipation.
The SGM61162A operates in pulse skip mode (PSM) at light load to boost light load efficiency, while the SGM61162B operates in forced pulse width modulation (FPWM) mode over the full load range to maintain constant frequency and reduce output voltage ripple.
The SGM61162 is available in a Green TSOT-23-6 package.
