DC-DC converters are used to transform a source of Direct Current (DC) from one voltage level to another. They are commonly used in applications such as power supplies, battery charging, and solar photovoltaic (PV) systems. The LMZ13608TZ/NOPB is a step-down DC-DC converter from Texas Instruments that can operate at a high input voltage (14V to 60V) and provide a low output voltage (1V to 52V). This converter is well suited for applications that require a stable output voltage over a wide input voltage range with a high efficiency. This article will discuss the application field and working principle of the LMZ13608TZ/NOPB DC-DC converter.

Application Field of the LMZ13608TZ/NOPB

The LMZ13608TZ/NOPB is primarily designed for use in space-constrained low-power applications. These applications may include but are not limited to industrial equipment, telecommunication systems, consumer electronics, portable computing systems, automotive applications, and embedded systems. With its wide input voltage range and high efficiency, this converter is an ideal choice for applications that require an output voltage to be regulated over varying input voltages with minimum power loss. Furthermore, the LMZ13608TZ/NOPB has a high frequency switching mode and a programmable duty cycle to further enable the efficient use of power.

Working Principle of the LMZ13608TZ/NOPB

The LMZ13608TZ/NOPB DC-DC converter works on the principle of Pulse Width Modulation (PWM) control. This control technique involves the application of a linear current regulation circuit in combination with a switching circuit. The linear current regulation circuit is responsible for maintaining the output voltage over varying input voltages. This is done by using a feedback control loop to compare the output voltage with a fixed reference voltage and adjusting the duty cycle of the switching circuit accordingly. The switching circuit consists of a series of transistors that rapidly switch the current on and off. This switching action is then used to raise or lower the output voltage accordingly.

The LMZ13608TZ/NOPB is designed to operate in the continuous conduction mode (CCM). This means that a constant current is flowing through the converter while operating. This current is then regulated by controlling the on and off times of the switching circuit. In addition to CCM, the LMZ13608TZ/NOPB also supports boundary conduction mode (BCM), enabling it to reduce the output capacitance and further increase power efficiency.

Overall, the LMZ13608TZ/NOPB DC-DC converter from Texas Instruments is a highly reliable, efficient, and cost-effective solution for low-power applications that require a stable output voltage over varying input voltages. The combination of the PWM control technique and dual-mode operation ensures that both cost and power savings can be achieved simultaneously.
