The new PowerWise Simple Switcher controller family includes four synchronous buck controllers well-suited for communications and industrial systems.
The LM3150 features an adjustable switching frequency and output voltage, and the LM3151, LM3152 and LM3153 feature a range of fixed frequencies along with a fixed 3.3V output voltage.
Input voltages for the controllers range from 6V to 42V with output current capability up to 12A. The controllers require minimal external components, which simplifies the design process and reduces the overall solution size. The controllers feature 93 per cent peak efficiency at load, positioning them among National’s PowerWise family of energy-efficient products. The controllers are easy-to-use components to design an efficient, medium-current, step-down power controller.
