The TPS57114QRTERQ1 is a highly-integrated, low-quiescent current and low-noise DC/DC switching voltage regulator. This device is equipped with a 300mV reference voltage and voltage range of 1.25V to 5.5V. It is an ideal power solution for portable electronic devices requiring high efficiency and good thermal performance. The TPS57114QRTERQ1 is a fixed-frequency, voltage-mode, current-mode, boost regulator featuring wide input and output voltage range, high current and quiescent current capability, external compensation and protection features.

The TPS57114QRTERQ1 is designed to provide a regulated output voltage from an unregulated input voltage. It uses synchronous rectification and current-mode control to optimize efficiency. The device can operate as either a Step-up (Boost) regulator or a Step-down (Buck) regulator. The device incorporates integrated MOSFETs, an internal voltage reference, and PWP and OVP circuitry. In addition, the device includes a true power good indicator, which can be monitored through an external resistor.

The TPS57114QRTERQ1 application field can be employed in various kinds of mobile, portable and industrial applications, such as notebook computer, cellular phone, tablet, wireless communication, digital camera, power tool, battery charger, and embedded system, etc. It provides many features like low quiescent current, 0.5% reference accuracy, and wide operating temperature range, etc.

The operating principle of the TPS57114QRTERQ1 can be divided into three stages: power-up, soft-start, and steady state. During power-up, the device will initialize and verify components before starting up. During the soft-start stage, the device will increase the output voltage slowly. Lastly, in the steady state, the device will output a stable voltage at a high efficiency, with the output voltage determined by the feedback network.

The TPS57114QRTERQ1 can operate at switching frequencies up to 1MHz. It is suitable for high frequency applications where a small inductor and capacitor are used. The built-in dynamic VOUT control can provide protection against overloading and shorting in the output stage. The device is designed to withstand up to 52V input voltage, thus allowing the design of power supplies with wide input voltage range.

The TPS57114QRTERQ1 is housed in a 4mmx4mm QFN package and is qualified for automotive applications. It also features thermal protection to prevent against overheating of the device. In summary, this device is suitable for power management in portable, low-voltage applications, or any application requiring highly efficient operation, low standby current, and protection from overcurrent, overvoltage, and overtemperature events.
