TPS53631RSBT is a special purpose voltage regulator designed for advanced computing and memory applications. This product provides system power and supports non-reference operation under extreme frequency and voltage operating conditions. It is optimized for applications with high frequency, high power and high output voltage constraints.

The TPS53631RSBT is a high-performance, single-ended, 6A, active-clamp, synchronous step-down regulator capable of delivering up to 6A of peak current. The device supports input voltages up to 20V and output voltages as low as 0.6V. The device also features a 2mV (max) gain accuracy, 100nA (min) Iq quiescent current, and up to 45,000 duty cycle under extreme frequency/voltage operating conditions. The part also has an array of protection features such as output overvoltage protection and input under voltage lockout with hysteresis.

The device is packaged in a high pin count, 24-pad QFN package with an exposed backside heat sink to improve thermal performance. The TPS52331RSBT is the ideal solution for high power applications requiring high power, low noise, fast transient response, and superior thermal performance.

The TPS53631RSBT application field includes Advanced Computing, Distributed Power, Memory, High Speed I/O, High End Networking and Communications, and High Speed ASICs. The device is specifically designed to provide power for applications with extreme frequency and voltage operating conditions, such as memory modules, graphics cards, CPUs, ASICs and high-speed I/O.

The working principle of the device is based on a single-ended, active-clamp synchronous step-down switch configuration. It consists of an integrated transistor, output regulator block and internal compensation block. The internal compensation block reduces output voltage ripple by providing a stable frequency response across a wide range of operating conditions. The device also features a high switching frequency of up to 5.5MHz for higher efficiency and fast transient response. The device also features an array of protection features such as undervoltage lockout, output over-voltage protection and over-current protection.
