National Semiconductor SIMPLE SWITCHER series power module three new products: high output voltage three easy to use for the different application load module can provide up to 3A and 6V drive current

National Semiconductor Corporation Ns announced the launch of three can drive high output voltage SIMPLE SWITCHER power module, these three new modules for different product markets, including industrial systems, communications infrastructure and military equipment market. Three models for power module LMZ14201H, LMZ14202H and LMZ14203H are not only easy to use, can also provide the same efficiency and synchronous switching regulator, and circuit design is also simple and linear regulator, so there is no need to add an external switching regulator like typical inductors and complex circuit layout.

The input voltage of LMZ14201H, LMZ14202H and rail LMZ14203H power module for 6V to 42V, and can provide high precision adjustable output voltage, the voltage value of up to 24V. Engineers can adjust the switching frequency by using only one resistor, which makes the circuit design more flexible.

That several power modules in addition to compatible with other models with pin series, integrated isolation inductor, its efficiency can be as high as 97%. Integrated inductors can reduce electromagnetic interference (EMI), so that these power modules comply with CISPR 22 class B electromagnetic wave radiation and conduction emission standards.

LMZ14201H, LMZ14202H load and LMZ14203H power module can drive 1A to 3A, the application architecture in the discrete point of load (POL) power supply system, and can generate the intermediate bus voltage in the system. Ultra high efficiency and superior thermal performance make these three power modules ideal for non ventilated cooling systems. In addition, these products and the use of special applications with the circuit, can generate -15V bias power supply, so that audio amplifiers (such as the U.S. National Semiconductor LME49880 chip) can get a wider dynamic range.
