The TPS54162QPWPRQ1 DC/DC buck-boost switched regulator is a member of Texas Instruments’ highly efficient, ultra-small TPS5416x family featuring ultralow quiescent current and tiny packages. This highly efficient, ultra-small, and high-performance regulator can turn a variable input voltage into a regulated and accurately controlled output voltage. The TPS54162QPWPRQ1 is best used in ultra-small computing, power management, and power-sipping applications where board space considerations are critical.

The TPS54162QPWPRQ1 is a highly efficient, integrated, two-phase DC/DC regulator designed to meet the requirements of low-voltage and low-power applications, such as portable and low-power consumer and embedded systems. The device is capable of maintaining a guaranteed 1A output current over a wide range of input voltages, and it also comes with built-in protection features such as over current, over voltage and thermal protection. The device also includes a power fail (PF) pin for under-voltage and over-voltage detection, as well as a current monitoring (COM) pin for internal monitoring.

The regulator works by using two phases to reduce the voltage drop while keeping the output current low. The first phase is called the boost phase in which the output voltage is increased to the intended level. The second phase is called the buck phase in which the output voltage is reduced to the intended level. This is done by passing the current through two power transistors in opposite directions, one bucking and one boosting the output voltage.

The output voltage is regulated and precisely controlled with the internal voltage feedback network, which features adjustable and very precise reference voltage. The device has a wide input voltage range from 4.5V to 17V, and the output voltage can be adjusted from 0.8V to 6V. The device also features a wide output current range from 0.15A to 1A. The internal peak current-mode control and smooth transition between the buck and boost phases ensure reliable and consistent output voltage regulation.

The TPS54162QPWPRQ1 is an excellent choice when size is an issue, and it is capable of delivering superior performance in a wide range of applications. Its integrated over-current, over-voltage, and thermal protection circuitry offers robust protection against damage to the device and connected components. Furthermore, the device’s low quiescent current and tiny package make the TPS54162QPWPRQ1 an ideal choice for ultra-small, power-sipping applications.
