IntroductionThe EL7571CMZ is a special purpose, voltage regulator specifically designed for applications that require a highly efficient and small solution size. It is rated for an operating temperature range of 1.8V to 5.5V, with a single output of 20V, at peak output currents of up to 120mA. The LDO, or linear drop out regulator in this case, has a guaranteed dropout voltage of 0.3V. The EL7571CMZ is a very important component in a wide range of applications due to its features such as the widest voltage range of any other buck regulator.Function and Application FieldThe EL7571CMZ is an integrated voltage regulator particularly suited for buck topology and is typically used in consumer and industrial applications. It consists of a voltage regulator and an adjustable output voltage. The adjustable output voltage range is 0.8V to 1.5V, with ±0.1V accuracy. This makes it perfect for applications that require a small size, high efficiency and low quiescent current. It is ideal for powering devices such as cell phones, tablets, printers, servers, gaming consoles, embedded systems, and industrial electronics. In addition, the EL7571CMZ can be used in automotive, power management, and PoE applications.Working PrincipleThe output voltage of the EL7571CMZ is adjustable through a resistor/capacitor (RC) timing network. The concept behind this is simple, by varying the frequency of oscillation between the two outputs of the regulator, it is possible to control the output voltage. This is because the output voltage is a function of the duty cycle of the buffer amplifier, i.e., the ratio of the time when the low side output voltage is greater than the high side output voltage and vice-versa. Using the RC timing network it is possible to adjust the frequency of oscillation and thus the output voltage.In addition to this, the EL7571CMZ is equipped with advanced protection features such as overvoltage, overcurrent and over temperature protection. This ensures that the regulator can safely dissipate any current or voltage spikes without damaging the device itself or the components connected to it.ConclusionThe EL7571CMZ is a highly efficient and small-sized voltage regulator specifically designed for applications that require a small solution size, high efficiency and low quiescent current. Its adjustable output voltage range of 0.8V to 1.5V, with ±0.1V accuracy, makes it suitable for a wide range of applications such as cell phones, tablets, servers, embedded systems and industrial electronics. Its advanced protection features ensure that the device is protected from any current or voltage spikes to ensure safe operation.
