UC2707NG4

UC2707NG4 is a Power Management Integrated Circuit (PMIC) – Gate Driver which is mainly used as a synchronous buck converter in managing and controlling high-power devices. It provides high-efficiency, high accuracy and fast controlled power switching in a single package. The features that makes UC2707NG4 more superior and better than the rest products are its noise reduction, low standby power, current limit, programmable soft-start, output voltage regulation and short circuit protection. Apart from that, UC2707NG4 also provides improved power efficiency, inductor current sensing, and low-power operation.

The UC2707NG4 is designed with a number of blocks for power management and control, such as: The Gate Driver, MOSFET Driver, Voltage Regulation and Power Management Blocks.

The Gate Driver block consists of an internal bootstrap diode and two N-channel MOSFETs to provide reach-through drive capability. The Gate Driver allows for superior power efficiency, as the reach-thru helps reduce the external component count and, consequently the power wasted in operations on the common drain line. Moreover, the Gate Driver is protected by a self-limiting output current, thereby avoiding shorting conditions when powering up the external components.

The MOSFET Driver block provides fast switching times by driving both N-channel MOSFETs at higher speeds, while providing excellent thermal management. The MOSFET Driver is protected against transient over-voltages and over-current conditions, further increasing the reliability.

The Voltage Regulation and Power Management block provides adjustable soft-stop, low-side current-limit, output voltage control, and an adjustable power-on/off delay. The power down/up mode feature can be used to reduce power consumption during light-load operation (sleep mode). An Advanced Thermal Protection mechanism protects the device from excessive heat. This helps prevents damage to the device and ensure it lasts longer.

The UC2707NG4 is a highly efficient and high-performance device. It is suitable for a wide range of applications that require high-power control, such as automotive power electronics and industrial power supplies. This device is also perfect for battery-powered and systems that require low output ripple and noise, such as motor drivers and power supplies. With its improved features, the UC2707NG4 can provide reliable operation and safe control of high-power load with reduced component count, resulting in an improved power efficiency for the system.
