The ZSPM4013 current-mode synchronous step-down power supply product can be used in the commercial,
industrial, and automotive market segments. It includes flexibility for a wide range of output voltages and is
optimized for high efficiency power conversion with low R
switching frequency facilitates low-cost LC filter combinations. Additionally, the fixed-output versions enable a
minimum external component count to provide a complete regulation solution with only 4 external components: an
input bypass capacitor, an inductor, an output capacitor, and the bootstrap capacitor. The regulator automatically
transitions between PFM and PWM mode to maximize efficiency for the load demand.
