The SGM61160 is a peak current control, adaptive off-time Turbo? mode synchronous step-down DC/DC converter with power-save mode (PSM) and integrated power switches. The input voltage range is from 4.5V to 18V and the output is programmable between 0.765V and 5.5V with 6A maximum output current capability.
This device offers a cost-effective and low-component count solution for bus regulators and includes a rich set of features such as low standby current, PSM at light loads to maintain high light load efficiency. The adaptive off-time Turbo? mode control provides a fast transient response without external compensation component and seamless transitions between pulse width modulation (PWM) mode and PSM. The SGM61160 also has a proprietary feature that enables the device to adopt low or ultra-low equivalent series resistance (ESR) output capacitors, such as POS- CAP and SP-CAP or ultra-low ESR ceramic capacitors.
