Introduction

AI Translation

The TPS53317A device is an integrated field-effect transistor (FET) synchronous buck regulator designed primarily for DDR termination. It can provide a regulated output with a value of 1/2 VDDQ, and this output has sink and source current capabilities. The TPS53317A device operates in D-CAP+ mode, which is easy to use, requires fewer external components, and provides fast transient response. This device can also be used in other point-of-load (POL) regulation applications with a current requirement of up to 6A. In addition, the device supports a full 6A sink current output with strict voltage regulation. The device has two switching frequency settings (600kHz and 1MHz), and it provides integrated dropout support, external tracking function, pre-biased start-up, output soft discharge, integrated bootstrap switch, power-good function, under-voltage lockout (UVLO) protection function for the V5IN pin, and supports the use of ceramic and SP/POSCAP capacitors. The device supports an input voltage of up to 6V, and the output voltage is adjustable in the range of 0.45V to 2.0V. The TPS53317A device comes in a 3.5mm×4mm 20-pin very thin quad flat no-lead (VQFN) package (green, RoHS-compliant, and lead-free), which uses proprietary integrated MOSFET and packaging technologies. Its rated operating temperature range is from -40°C to 85°C.
