Working Principle

TPS62162QDSGRQ1 is a monolithic, synchronous step-down voltage regulator with a wide input and adjustable output voltage range. This switching regulator device is operated in pulse width modulation (PWM) mode. It employs a fixed frequency PWM architecture. The switching frequency is 300 kHz.

The internal linear regulator is enabled when the EN pin is held below 0.3 V, and disabled when EN pin is pulled above the high threshold voltage VPTS. An external resistor divider circuit is used to set the output voltage. Also, an external RC network is used to control the current slew rate at the output voltage rising or falling edges.

This regulator device also has several integrated control and protection features. Fault conditions such as overtemperature, short-circuit, undervoltage and overvoltage, are sensed and protected against by turning off the switch and by generating a latch off signal at UVLO and TON pin. The device also features an overvoltage protection (OVP) circuit, which monitors the output voltage rise, and shuts down the device if the voltage is above preset threshold level.

Conclusion

In conclusion, the TPS62162QDSGRQ1 device is one of the most advanced switching voltage regulator ICs, featuring a wide input and adjustable output voltage range, high efficiency, programmable output voltage, external clock synchronization input, and integrated fault protection circuitry. It is suitable for a wide range of applications, such as in battery-powered devices, notebooks, cellular phones, and automotive and industrial applications.
