TPS62355DRCR is a high-performance, high-precision, low-noise, low-temperature, low-power, and low- power DC/DC switching regulator. It is manufactured by Texas Instruments, suitable for use in applications such as portable electronics, battery-operated hand-held devices and automotive systems. The device has been designed to provide a reliable, efficient and cost effective solution for powering applications requiring extreme accuracy and low power consumption. The TPS62355DRCR switch regulator comes with a number of features such as a wide input voltage range, low quiescent current, fast transient response, high accuracy and a P-Channel MOSFET driver.

The device is a dividing mode DC to DC converter with an adjustable output current capability. It works by switching an integrated P-Channel MOSFET transistor on and off to control the output voltage. When enabled, the transistor, which is connected to an external inductor, charges up an external capacitor which is connected to the output voltage. This inductor-capacitor pair is tuned so it maintains a constant internal regulation point. When the external load on the output changes, the TPS62355DRCR senses the drop in voltage, adjusts the current to the FET, and helps maintain the output voltage. The TPS62355DRCR switch regulator is also able to operate in the discontinuous mode to further extend battery life.

The operating temperature range for the device is from -40°C to +125°C. The device also supports a wide input voltage of 2.5V to 5.5V, making it suitable for most applications. The TPS62355DRCR switch regulator also has low quiescent current of 10µA at 3V input voltage and adjustable outputs voltages which can be adjusted down to 0.8V. The output voltage range is adjustable from 0.8V to 5.5V. It also features fast transient response and high accuracy. The accuracy of the output is within ±2.5% over the operating temperature range. It also has a low-noise operation of just a few microvolts, making it suitable for most noise sensitive applications.

The device also has Thermal Shutdown, Short Circuit protection, and Over-Current protection, making it safe to use in many applications. The TPS62355DRCR switch regulator is available in two packages, the 3mmx3mm UQFN and the 5mmx5mmVQFN packages.

Applications for the TPS62355DRCR switch regulator include hand-held devices, portable electronics, automotive systems, and other battery-powered equipment such as Point Of Sale (POS) systems that require a low-power, high-accuracy and low-noise DC/DC switching regulator. It is also suitable for use as a step-down regulator for portable/mobile products, wireless communication systems, power management systems, and STB (Set Top Box) products.
