The TPS51220ARSNT is a monolithic high-efficiency, synchronous step-down (Buck) DC/DC converter. It is a special purpose Voltage Regulator that is specifically designed to improve power dissipation, reduce EMI, and optimize the transient response of load steps in automotive and other battery-powered applications. This Voltage Regulator has an internal current-mode control scheme, as well as an advanced PWM scheme for controlling the output regulator. It also has a built-in input voltage boost stage, which ensures a stable output voltage from a wide input voltage range.
The TPS51220ARSNT Voltage Regulator uses synchronous rectification and internal MOSFETs to reduce power losses and output ripple. A high switching frequency of up to 2 MHz lowers both input and output voltage ripple and allows for a small inductor and capacitor design. The device also supports continuous, pulse-skipping, and dual-output modes for a variety of application requirements.
The TPS51220ARSNT is an ideal Voltage Regulator for automotive systems, battery-powered applications such as portable medical equipment, wireless communication, and IoT (Internet of Things) nodes. It is also ideal for industrial and networking applications such as industrial controllers, digital power supplies, power conditioners, and solar inverters. As compared to conventional linear regulators, the TPS51220ARSNT provides a higher efficiency, smaller solution size, lower power dissipation, and higher quality output voltage.
The TPS51220ARSNT adopts a current-mode control design and is capable of providing regulated output voltages from 0.6 V to 5.25 V with an operating input supply range of 4.5 V to 36 V. This Voltage Regulator achieves up to 95% efficiency under optimal conditions, allowing for extended battery life. The frequency of operation is adjustable from 100 kHz to 2 MHz, allowing for the design of extremely small inductors and capacitors. The device also offers built-in hysteresis and foldback overcurrent protection. Protected programming functions and high accuracy (±2%) Also make this device an optimal solutions for many automotive, commercial and consumer low-voltage applications.
The TPS51220ARSNT is a monolithic synchronous step-down (Buck) DC-DC converter with integrated power MOSFETs. It is specifically designed to offer low solution cost, high efficiency and low EMI in automotive and other battery-powered applications. It has two versions, one of which includes an internal 4.5V to 9V voltage boost stage that allows it to operate over a wide input voltage range of 4.5 V to 36 V. It features an auto-compensation controlled current-mode design with adjustable output current limit, adjustable switching frequency from 100 kHz to 2 MHz and a single power stage design that simplifies board layout and reduces component count. The device also has a built-in write protect for system security, under-voltage lockout, thermal protection, and soft start functions.
The TPS51220ARSNT synchronous buck DC/DC voltage regulator is a special purpose Voltage Regulator that is specifically designed for automotive and other battery-powered applications. It boasts superior efficiency and low EMI performance and offers an extremely cost-effective solution for low-voltage applications. With over voltage protection, low quiescent current, internal MOSFETs, and adjustable switching frequency and current limiting, the TPS51220ARSNT is an ideal solution for automotive, industrial, and consumer applications.
