The TPS621361RGXR (TPS62136) is a synchronous step-down power supply buck converter used to convert the voltage of a power supply to a smaller voltage. It is a member of the Texas Instruments TPS6213x family of buck converters. TPS62136 is a high-efficiency device featuring a low start-up current, low noise, and fast transient response.

The TPS62136 is a single-stage, synchronous buck converter that can deliver up to 8 A of output current with good step-down performance and excellent efficiency. The device uses an advanced internal switch technology, allowing it to achieve excellent efficiency numbers and a very low no-load power consumption. The TPS62138 can deliver up to 8 A of continuous current at a switch frequency of 2.2 MHz and a VIN range of 3.2 V to 17 V and established output voltages from 0.8 V to 2.9 V.

The TPS621361RGXR application field includes automotive, industrial and general embedded applications. The TPS621361RGXR device is ideal for dealing with power-input voltage signals that can vary significantly during operation and requires excellent transient performance. It can be used in applications such as low-voltage DC to DC converter, solar module, communication module, display module, automotive application, wireless communication, battery-powered DC to DC converter, etc.

The TPS621361RGXR working principle is based on the typical buck converter topology. The device uses a low on-resistance power switch, allowing it to achieve high efficiency. The TPS62136 also employs an internal clock. The duty cycle of the power switch determines the output voltage. A high frequency synchronous rectifier is used to quickly recover energy wasted during the conduction of the switch. A feedback circuit senses the output voltage, comparing it to a reference voltage and adjusting the duty cycle of the switch in order to maintain the output voltage at the desired value.

The TPS621361RGXR features low start-up and operating currents, fast transient response, low noise and steady-state ripple, and easy synchronization to an external clock. An internal linear regulator supplies power to the control logic and other components. The device is designed with a few external components and allows for easy implementation and cost savings. The package is small and the part can be easily mounted onto a printed circuit board.

The TPS621361RGXR is a versatile and cost-effective member of the Texas Instruments TPS6213X family of buck converters. It works perfectly for automotive, industrial, and general embedded applications. Its performance, size, and simple design make it an ideal choice for applications requiring low power consumption and high efficiency.
