TPS62171DSGT is a high efficiency, low noise, DC/DC switching regulator from Texas Instruments, specially designed for powering applications which need a small size, high current and efficient step up converter with application in various electronic devices, such as lithium-ion battery charging and high current applications, like USB wall chargers. It is a great solution for both low and high power demands, with very low quiescent current and reduced operating temperature, making it suitable for battery powered applications.The TPS62171DSGT is a triple-output DC/DC switching regulator that offers up to 95% efficiency and a wide input voltage range up to 6.5V. This switching regulator is available in a single-output configuration in three package types, a QFN16, a TSSOP16 and a DDPAK/DFN10.The part features an adjustable output voltage of 2.85V to 6.0V and an adjustable output current of up to 5A. It operates from an input voltage range of 2.7V to 6.5V and over-temperature protection is provided. This regulator operates with a wide frequency range from 500 kHz to 2.2 MHz using a single supply voltage with an adjustable current limit.Working PrincipleThe TPS62171DSGT DC/DC switching regulator features an integrated P-channel power MOSFET and an N-channel MOSFET operating in a buck-boost configuration. When the switch connects the input to the drain of the N-channel MOSFET, the power is transferred from the input to the N-channel MOSFET and the inductor current increases. When the N-channel MOSFET acts as a switch, it turns off and the energy stored in the inductor is transferred to the output and discharged. During this time, the P-channel MOSFET will turn on and the current and the inductor energy is transferred to the output. The P-channel MOSFET is constantly alternating between on and off states during each switching cycle as it transfers energy from the input to the output.The output voltage of the TPS62171DSGT is regulated by controlling the duty cycle of the P-channel MOSFET switching. The feedback control comparator monitors the output voltage and the error amplifier adjusts the duty cycle to ensure the desired output voltage is maintained.Application FieldThe TPS62171DSGT device is especially suitable for automotive, industrial, and mobile device applications, using a wide input voltage range from 2.7V to 6.5V and an adjustable output voltage, adjustable current limit and up to 95% efficiency.It can also be used in applications that require high current and high efficiency, such as USB wall chargers, data line protection, and system controllers. It is an energy efficient solution for lithium ion battery charging and can provide up to 5A of peak output current at high efficiency.ConclusionThe TPS62171DSGT is a high efficiency, low noise, DC/DC switching regulator from Texas Instruments designed for powering applications in various electronic devices. It is an excellent choice for low and high power demands with very low quiescent current and reduced operating temperature, making it suitable for battery powered applications. The wide input voltage range, adjustable output voltage, adjustable current limit and up to 95% efficiency makes it an ideal device for applications such as USB wall chargers, data line protection and system controllers.
