The LM2670SD-12 is a voltage regulator from the Texas Instruments family of PMICs, DC – DC switching regulators specifically. Designed for use in synchronous buck converters or DC-DC switches in a very small form factor, this regulator features exceptionally low output voltage ripple, and adjustment range of 1.23V to 19V. With its internal current limit, this regulator can be used in the adjustable and fixed output voltage applications. It also has an external Shutdown pin that can be used to reduce the power consumption when the load is inactive.
The design of the LM2670SD-12 is based on a buck converter architecture. It comprises of an input capacitor, an inductor, a transformer, an output capacitor and a bypass capacitor, as well as several transistors, diodes and resistors. When the voltage regulator is enabled, the input capacitor is energized from the DC source. The pulse width modulation (PWM) computes the correct duty cycle of the transistor or switch to regulate the output voltage. This PWM is created by the voltage feedback to the error amplifier. Since this control loop is closed, the output voltage will be regulated to a desired value.
The inductor is charged with energy from the source whenever the switch is turned on. When it reaches the level set by thecurrent limit, the switch is opened and the energy stored in the inductor is discharged, and then transferred to the secondary side of the transformer through the primary winding. The rectifier on the secondary winding converts the alternating current (AC) to a direct current (DC), and then it is filtered by the output capacitor. The bypass capacitor is connected in parallel with the output capacitor to reduce the output voltage ripple. The inductor current is continuously monitored to keep the output voltage constant.
The LM2670SD-12 consists of a wide array of features, including over-temperature protection, Under Voltage Lockout (UVLO) and soft-start. Its adjustable input voltage range extends from 2V to 42V, making it suitable for a wide range of power application. And its adjustable output current is capable of sourcing up to 2A. In addition, it has high efficiency up to 93%, and a pulse-by-pulse current limit, making it one of the most efficient and economical voltage regulators available.
Overall, the LM2670SD-12 is an ideal choice for a cost-effective, energy efficient and high performance voltage regulator solution. It is well suited to a wide range of applications, such as electronic point-of-sale payment systems, mobile battery chargers, automotive equipment, personal computers and much more. With its small form factor, adjustable design, robust performance and wide input/output range, the LM2670SD-12 is an excellent choice for a variety of power management solutions.
