DC-DC converters are electronic devices designed to modify an input voltage to a specific output voltage with a certain power rating. The LMZ14202TZ-ADJ/NOPB, is a synchronous step-down DC-DC buck converter that efficiently converts an input voltage of up to 36V to an output voltage as low as 0.6V. It is highly efficient and boasts a peak efficiency of up to 97%. As one of the coolMOS™ P7-series of DC-DC converters, it is also suitable for extremely low-noise working sites. Furthermore, the LMZ14202TZ-ADJ/NOPB needs no components, eliminating the hassle of sourcing and ruling out procurement delays.

The LMZ14202TZ-ADJ/NOPB features an integrated synchronous rectifier that minimizes switching losses, as well as reducing the input and output ripple. It also has a PWM controller with a voltage mode control based on the reference of an external timing capacitor, and an integrated 0.8V reference that allows the external standing current sense resistor to be omitted. The device is also programmable with an external resistor. An external soft-start capacitor is also integrated to help reduce inrush currents. The device also offers an optional enable pin to enter or keep the device in a low power, shutdown mode.

The LMZ14202TZ-ADJ/NOPB provides a high level of protection, which reduces component count and extends its lifetime. These protections include over-voltage, over-temperature, and short-circuit protection. This high level of protection also eliminates the potential need for output decoupling, which further limits the component count of the design. All of these features make the LMZ14202TZ-ADJ/NOPB an ideal choice for many converters.

The LMZ14202TZ-ADJ/NOPB can be used in a wide range of applications, including those with highly efficient power supplies, such as consumer, industrial, and automotive. It is also ideal for low-noise, high-current applications, such as those involving LED lighting and active-cooling systems. The LMZ14202TZ-ADJ/NOPB’s high efficiency and robust protection make it ideal for mission-critical applications in the medical and avionic industry, as well as in IT and telecom equipment. The wide input voltage range of up to 36V, along with its many other features, makes the LMZ14202TZ-ADJ/NOPB a versatile solution for many converter applications.

The working principle of the LMZ14202TZ-ADJ/NOPB is based on a synchronous (or voltage-mode) buck converter design. The input voltage is first used to drive an internal MOSFET, with the current regulated by an internal PWM controller. This PWM controller then uses the external timing capacitor to adjust the output voltage, while the output of the MOSFET is then rectified by an integrated synchronous rectifier. This allows for a higher efficiency, as well as a lower output ripple.

The LMZ14202TZ-ADJ/NOPB is a highly efficient, robust, and versatile DC-DC converter that can be used for a variety of applications. It features a wide input voltage range, high efficiency, and integrated protection, making it an ideal solution for many DC-DC converter applications.
