SGM6618A
23V VIN, 25V VOUT, 6A, High-Efficiency, Synchronous Boost Converter with Programmable Peak Current Limit
The SGM6618 family is a high-voltage synchronous Boost converter that offers high efficiency and a small size with its integrated 41mΩ low-side and 33mΩ high-side power switches. The SGM6618 family has a wide input voltage range of 2.9V to 23V and provides an adjustable output voltage between 4.5V and 25V, with a switching current capability up to 6A.
The SGM6618 family utilizes the constant off-time peak current control topology for output voltage regulation， which provides enhanced dynamic performance. The device operates in PWM mode under heavy load conditions and automatically switches to PFM mode at light load, maintaining high conversion efficiency across the entire load range. The SGM6618 family operates in pulse width modulation (PWM) mode under moderate to heavy load conditions. For light load condition, the device provides a choice between two operating modes, selected by the MODE pin. One is pulse frequency modulation (PFM) mode, which is used to achieve high light load efficiency. The other is forced PWM mode, which keeps the switching frequency constant to avoid audible noise and other application problems caused by low switching frequency.
The SGM6618 family integrates a programmable peak switching current limit function and a soft-start function. The SGM6618 family also implements various protection features, such as output over-voltage protection (OVP), cycle-by-cycle over-current protection (OCP), and thermal shutdown to improve device robustness.
The SGM6618 family is available in a Green TQFN- 2.5×2-13L package.
