TPS59116RGER

The TPS59116RGER is a synchronous buck controller with an integrated driver. It is designed for low quiescent current and wide input voltage range buck switching regulator applications. It features step-down 4-switch FET architecture, integrated high-side FET with integrated driver, and programmable current-limit protection. This combination of features simplifies design and makes the TPS59116RGER ideal for battery-powered and automotive applications such as charging and powering electronic devices.

The TPS59116RGER comes with a wide input voltage range of 4.5V to 28V, allowing it to be powered by battery, AC-DC or DC-DC converters. This integrated switcher provides high efficiency and fast transient response while reducing design size and component count. Additionally, it supports wide output range, starting from 0.6V up to 4.0V with 4.6A output current capability.

The TPS59116RGER features an integrated high-side FET driver with different levels of drive strength for an optimized combination of speed and efficiency. The device can deliver up to 95% efficiency over a wide load range and has a complete suite of protection features to ensure safe operation in harsh conditions. This includes under-voltage lockout (UVLO), programmable output current limit and thermal shutdown. In addition, the integrated soft-start, bypass current and skip modes help reduce system stress and improve device reliability.

The TPS59116RGER is designed for applications where space is a premium and cost is a consideration. These include power management solutions for embedded systems and consumer applications, such as industrial, automotive, telecommunications and consumer electronics. To simplify the design process and reduce total power dissipation, an inverted flyback topology is used for low noise and fast transient response. With its low quiescent current and wide input voltage range, the TPS59116RGER can provide an optimal cost/performance ratio for applications such as automotive and embedded system power management.

The TPS59116RGER working principle is based on the typical voltage regulator circuit, which includes an input voltage source, an output voltage P-FET switch and an internal control circuit. The control circuit is programmed and configured with some external components to regulate the output voltage according to the set point. The controller Comparator compares the reference voltage with the Feedback voltage and accordingly turns the FET switches ON and OFF. This switching ON/OFF technique converts high input voltage to the desired output voltage. The current-limit protection is provided by an external sense resistor. This ensures that the load does not draw more current than the configured limit. Furthermore, the protection features of the device, such as soft-start, over-temperature, and under-voltage lockout protect both the device and the load from excessive currents, voltage levels and temperature.

Overall, the TPS59116RGER is an efficient, low-cost synchronous buck controller with an integrated driver that offers quick transient response, low quiescent current, wide input voltage range and integrated protection features. It is designed for low power consumption and can provide optimal performance in a wide range of applications, including automotive, industrial, and consumer electronics.
