Description
The MPQ4468 is a frequency-programmable (350kHz to 2.5MHz), asynchronous, step-down switching regulator with an integrated internal
high-side power MOSFET. It provides up to 3.5A of highly efficient output current with current mode control for fast loop response.
The wide 3.3V to 36V input range accommodates a variety of step-down applications in automotive input environments, and is ideal for batterypowered applications due to its extremely low quiescent current.
The MPQ4468 employs AAM (advanced asynchronous modulation) mode, which helps achieve high efficiency in light-load condition by
scaling down the switching frequency to reduce switching and gate driving losses.
Standard features include soft start (SS), external clock sync, enable (EN) control, and a power good (PG) indicator. High duty cycle and
low dropout mode are provided for automotive cold-crank condition.
Over-current protection (OCP) is employed to prevent the inductor current from running away. Hiccup mode greatly reduces the average
current in short-circuit condition. Thermal shutdown provides reliable, fault-tolerant operation. The MPQ4468 is available in a QFN-16
(3mmx4mm) package.
