TPS60124PWPG4 is an advanced DC/DC buck switching regulator designed for battery operated applications. It consists of integrated power MOSFETs, current mode controller and an internal compensation network. It is capable of driving up to 2A of continuous current at an output voltage of 1.2V with internal compensation. The key features of the TPS60124PWPG4 include input voltage range of 2.7V to 5.5V, adjustable switching frequency of up to 2MHz, PFM/PWM automatic mode with low (<1000μA) quiescent current, programmable start-up time and Enable pin for power effect sequencing.The TPS60124PWPG4 can be used in a variety of applications such as handheld electronic devices, cameras, smartphones, PDAs, and battery powered equipment. It is especially suitable for cases where power optimization, size or battery life considerations are paramount. In addition, the TPS60124PWPG4 is suitable for powering peripherals such as displays, storage elements, and power amplifiers from a single 5V battery.The TPS60124PWPG4 is a highly integrated DC/DC switching regulator device capable of power conversion over a wide input voltage range, delivering output currents up to 2A. Its basic topology, consisting of an internal power MOSFET switch and current mode control circuitry, allows it to be used in a variety of configurations, including voltage-in, current-out mode and current-in, voltage-out mode.The TPS60124PWPG4 works by regulating the output voltage by switching the internal power MOSFET between two states: on and off. In the on-state, the switch is shorted between its two source terminals, while in the off-state, the switch (acting like an open circuit) prevents current from flowing between the two source terminals. The current mode architecture of the TPS60124PWPG4 also allows for programmable current limiting, which helps to protect the circuit from being overloaded.The output voltage of the TPS60124PWPG4 can be programmed with a single external resistor divider network, allowing for freedom in the design of the output voltage. For example, if the output voltage is 1.2V, the ratio of the two external resistors, R1 and R2, can be selected to give the required output voltage. The TPS60124PWPG4 is also capable of setting a maximum current limit in order to protect the load from current overloads. This is achieved by connecting an external resistor R3 between the two source terminals of the PMOS switch.The TPS60124PWPG4 evaluation module is an ideal development and evaluation tool for the device. The circuit board connected to the TPS60124PWPG4 allows for easy configuration of the device, including setting the output voltage, current limits, and switching frequency. The module also features an enable pin (EN) which allows the device to be enabled or disabled, ensuring power sequencing when multiple devices are used in a circuit.In summary, the TPS60124PWPG4 is a highly efficient and compact DC/DC buck switching regulator for battery-powered applications. It offers output voltage accuracy and enables flexible power management and sequencing. The device is capable of easy programming and fast, low-noise switching frequencies up to 2 MHz. It is therefore ideal for a broad range of design applications.
