CS5212
Low Voltage Synchronous
Buck Controller
The CS5212 is a low voltage synchronous buck controller. It
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
DS(on)
NFETs for
better efficiency. The V
2
control architecture is used to achieve
unmatched transient response, the best overall regulation and the
simplest loop compensation.
Additionally, the CS5212 provides overcurrent protection,
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.
