TPS62171QDSGTQ1

The TPS62171QDSGTQ1 is a small, switch-mode voltage regulator designed for small and low-power applications. It features a wide input voltage range, low operating current and a large output capacitor for longer hold-up time. The device is suitable for applications with tight load transients and high efficiency DC-to-DC conversion with limited board space.

The TPS62171QDSGTQ1 is a DC-DC switching voltage regulator that operates over an input voltage range of 6.5 V to 16.5 V and provides an output voltage up to 5 volts with adjustable current limit and temperature protection. The device provides high efficiency and excellent line and load regulation. The switching frequency is adjustable through an external resistor. It also features an Enable-input pin to control or shut-off the device. The device is available in a tiny QFN-16 package.

The TPS62171QDSGTQ1 is primarily intended for use in low power applications that require a low component count and high efficiency. It can be used in a variety of products such as industrial, automotive and consumer electronics. The device is also suitable for use in distributed power systems.

The TPS62171QDSGTQ1 uses a synchronous buck topology architecture with a power MOSFET as the switch. An internal control circuit provides output regulation and protection functions. The device regulates an output voltage to millivolt accuracy and maintains tight line regulation over temperature and line input variations. It operates in the switching-mode over a wide input voltage range and provides an adjustable output current limit.

The TPS62171QDSGTQ1 provides over-temperature shut-down protection by limiting the output voltage and current when the junction temperature exceeds an internal threshold. It also has a Current Limit Enable/Disable pin, which allows the user to enable of disable a soft-stop over current protection feature.

In addition, the TPS62171QDSGTQ1 has an Enable-input pin which provides a logic-high or logic-low enable/disable function. A logic-high enables the device while a logic-low shuts it off making it suitable for power sequencing applications. It also has an external resistor that can be used to adjust the switching frequency of the device.

The TPS62171QDSGTQ1 is a highly integrated, small, efficient and low standby current consumption DC-DC converter, which makes it ideal for a variety of applications. The device has been validated to meet reliability, safety and performance requirements mandated for automotive applications.
