contains all required circuitry for a synchronous buck converter using

external N–Channel MOSFETs. High current internal gate drivers are

capable of driving high gate capacitance of low R

better efficiency. The V

unmatched transient response, the best overall regulation and the

simplest loop compensation.

undervoltage lockout, soft start, built–in adaptive non–overlap, and an

adjustable fixed frequency range of 150 kHz to 750 kHz, which gives

the designer more flexibility to make efficiency and component size

trade offs. The CS5212 will also operate over a 3.1 V to 7.0 V range

using either single or dual input voltage.
