Description
The MPQ4467 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 2.5A 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 battery-powered applications due to its extremely low quiescent current.
The MPQ4467 employs AAM (advanced asynchronous modulation) mode, which helps achieve high efficiency in light-load conditions by scaling down the switching frequency to reduce the switching and gate driver 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 conditions.
Over-current protection (OCP) is employed to prevent inductor current runaway. Hiccup mode greatly reduces the average current in a short-circuit condition. Thermal shutdown provides reliable, fault-tolerant operation.
The MPQ4467 is available in a QFN-16 (3mmx4mm) package.
