MPQ9841A-AEC1

36V, 1A, Low-I_Q, Synchronous Step-Down Converter, AEC-Q100 Qualified

概要

The MPQ9841A-AEC1 is a high-frequency, synchronous, rectified, step-down switch-mode converter with built-in power MOSFETs. It offers a very compact solution that achieves up to 1A of continuous output current (I_OUT), with excellent load and line regulation across a wide 3.3V to 36V input supply voltage (V_IN) range.

The switching frequency (f_SW) can be configured or synchronized to an external clock between 350kHz and 2.5MHz. Synchronous operation and an ultra-low, 14μA sleep-mode quiescent current (I_Q) provide high efficiency across the I_OUT load range. This allows the MPQ9841A-AEC1 to be used in a variety of step-down applications in automotive input environments and battery-powered applications.

Peak current mode provides fast transient response and eases loop stabilization. Excellent low-dropout performance allows the MPQ9841A-AEC1 to be used in high duty cycle applications.

Full protection features include over-current protection (OCP), short-circuit protection (SCP), and thermal shutdown. An open-drain power good (PG) signal indicates whether the output is within 10% of its nominal voltage.

The MPQ9841A-AEC1 is available in a space-saving QFN-16 (3mmx4mm) package, and is available in AEC-Q100 Grade 1.
