Voltage regulators are important components which are frequently used in current power supply design. The LX1672-06CLQ is a high performance DC-DC switching controller from Texas Instruments. It is specifically designed for cost-effective intermediate bus voltage conversion applications. This controller operates in a synchronous buck switching regulator mode, allowing for a regulated output voltage with a fast transient response.

The LX1672-06CLQ provides excellent line and load regulation performance. It is capable of delivering up to 6A output current with minimal external components.

The LX1672-06CLQ can operate with a wide variety of input and output voltages. The input voltage range can be as low as 2.5V and as high as 28V, while the output voltage range can be as low as 0.7V and as high as 28V. In addition, the device’s output voltage can be adjusted from 7.2V-17V, which allows for very precise voltage regulation.

The LX1672-06CLQ operates in a synchronous buck configuration. The device’s power MOSFETs provide both very low on-resistance and very low switching losses. The device employs an integrated logic-controlled PWM oscillator, which ensures a controlled transition between the on and off states of the device. This prevents overshoot and ringing at the output during the transition. The device also has an undervoltage lockout feature which prevents startup under low battery conditions.

The LX1672-06CLQ is equipped with an internal compensation circuit which ensures an optimized loop response over the entire output voltage range. The device also has a cycle-by-cycle current limit protection, which prevents the device’s output current from exceeding 6A. This current limit protection feature is adjustable, allowing for the nominal current limit to be decreased for higher output loads.

The LX1672-06CLQ is ideally suited for applications such as automotive, industrial, telecom and networking applications, as well as other AC/DC power conversion applications. The device’s wide input and output voltage ranges, fast transient response, and high current output capabilities make it a very attractive solution for cost-effective intermediate bus voltage conversion applications.
