The TPS65263QRHBRQ1 is a voltage regulator designed for both the industrial and automotive markets. This integrated circuit features high-efficiency DC/DC conversion, programmable UVLO functionality, Power Good and Fault Status flags, an integrated adjustable linear regulator, as well as diagnostics to protect against thermal and short-circuit faults.

The TPS65263QRHBRQ1 works as a DC/DC step-up voltage regulator and is suitable for any automotive or industrial application requiring a supply voltage of up to 5V. This integrated circuit can provide output voltages from 1.2V to 10V, achieving efficiencies up to 95%.

The integrated linear regulator can be used to generate low-voltage supplies in the 0.95V - 5V range, with output current up to 100mA. The device employs the Pulse Frequency Modulation (PFM) topology, and achieves a wide input voltage range of 4.4V to 36V.

The TPS65263QRHBRQ1 is also equipped with integrated protection circuits including an adjustable Under-Voltage Lockout (UVLO) circuit, a thermal shutdown, as well as over-voltage, over-current, and short-circuit protection.

The device also incorporates a Power Good (PG) signal, which indicates when the output voltage has reached and has stabilized within 90% of its designed value. The device also provides an actively monitored fault status indicator, which alerts the user to any potential fault condition; these conditions include an output over-voltage, output under-voltage, a short circuit at the output, an over-temperature, or input under-voltage.

The TPS65263QRHBRQ1 makes use of surface-mount technology (SMT), and is available in the SU-81 package with a maximum junction temperature of +125°C. It is designed to be placed with a minimum ground and power layer separation, and features an exposed pad for improved thermal performance.

Overall, the TPS65263QRHBRQ1 voltage regulator is designed to meet the requirements of both automotive and industrial applications, where it can provide efficient DC/DC conversion and protection against fault conditions.
