Product Description

The EV4430-L-00A is an evaluation board for the MP/MPQ4430GL. The MP/MPQ4430GL is a frequency-programmable (350kHz to 2.5MHz), synchronous, step-down, switching regulator with integrated internal high-side and low-side power MOSFETs. It provides up to 3.5A of highly efficient output current with current mode control for fast loop response.

The MP/MPQ4430GL employs AAM (advanced asynchronous modulation) mode which helps to achieve high efficiency under light-load conditions by scaling down the switching frequency to reduce the switching and gate driver losses.

The EV4430-L-00A is a fully assembled and tested evaluation board, and generates 3.3V output voltage at load currents up to 3.5A, from a 3.3V to 36V input range. It is AEC-Q100 qualified, and is available in a QFN-16 (3mmx4mm) package.

Parametrics

36V, 3.5A, Low Iq Synchronous Step-Down Converter AEC-Q100 Qualified

The MPQ4430 is a frequency programmable (350k to 2.5MHz) synchronous step-down switching regulator with integrated internal high-side and low side power MOSFET. It provides 3.5A (or less) highly efficient output with current mode control for fast loop response.

36V, 3.5A, Low Quiescent Current, Synchronous, Step-Down Converter AEC-Q100 Qualified

The MP4430 is a frequency-programmable (350kHz to 2.5MHz), synchronous, step-down, switching regulator with integrated, internal, high-side and low-side power MOSFETs. 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 battery-powered applications due to its extremely low quiescent current.
The MP4430 employs advanced asynchronous mode (AAM), 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 synchronization, 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) with valley-current detection is employed to prevent the inductor current from running away. Hiccup mode reduces the average current in short circuit condition greatly. Thermal shutdown provides reliable and fault-tolerant operation.
The MP4430 is available in a QFN-16 (3mmx4mm) package.
