TPS62229DDCR, a high-efficiency DC-DC switching regulator from Texas Instruments, is a point-of-load, synchronous step-down integrated circuit. It is designed for clocked applications that require continuous input-voltage regulation and small size.
The TPS62229DDCR features a wide input voltage range of 2.7V to 5.5V and a maximum output current of 2A. It has a switch-node output voltage adjustable from 0.8V to VIN1, while VIN1 is nominally connected to the input voltage, VIN. This regulator is capable of achieving up to 97% efficiency and high power-conversion density due to its unique low-RDS(on) internal power switch and synchronous high-side and low-side MOSFETs. Its integrated logic control, high-performance compensation, and top and bottom cascode MOSFETs allow for stable, fast transient response, simple design and operation over a wide input and output voltage range.
The TPS62229DDCR uses a pulse width modulation (PWM) control technique to regulate the output voltage. Its built-in loop compensation provides a fast response to changes in the output voltage, as well as precise voltage regulation and low output voltage ripple. The integration of the dual-N-MOSFETs, compatible with 5V logic levels, provides fast transient response and low output voltage ripple during load and line transients.
The TPS62229DDCR is capable of supporting up to 2.0A of continuous output current and is particularly suited for applications that require high efficiency and precise regulation of the output voltage. It is able to withstand transients down to 2.7V and has a maximum output switch current of 6.5A. It is ideal for a wide range of portable applications such as mobile phones, PDAs and handheld computers as well as many industrial, communications and automotive applications.
The TPS62229DDCR application field covers a wide spectrum, from cell phones to industrial controllers. It can be used in communications and networking equipment, such as switches and routers, as well as medical equipment and instrumentation. The efficient performance of this device makes it well suited for use in battery-powered applications, where its small size, wide input voltage range and high power-conversion efficiency make it an ideal choice.
The TPS62229DDCR is an excellent choice for DC-DC voltage conversion applications that require precise, efficient and stable output-voltage regulation. It integrates an internal power switch, dual synchronous MOSFETs and efficient loop compensation to ensure accurate and fast transient response, making it ideal for high-current applications. With its wide input voltage range and high output current, it is suitable for a wide range of applications.
