Description
The MPQ4326M-AEC1 is a configurable-frequency (200kHz to 2.5MHz), synchronous, step-down switching regulator with integrated internal high-side and low-side power MOSFETs (HS-FET and LS-FET, respectively). It features integrated input capacitors to optimize EMI performance, and can provide up to 6A of highly efficient output current (IOUT) with peak current mode control.
The MPQ4326M-AEC1 can maintain a regulated output voltage (VOUT) across a wide input voltage (VIN) range up to 36V. Over-voltage protection (OVP) allows the device to survive load dumps up to 42V. A 1μA shutdown mode quiescent current (IQ) allows this device to be used in battery-powered applications. High power conversion efficiency across a wide load range is achieved by scaling down the switching frequency (fSW) at light loads to reduce switching and gate driver losses.
An open-drain power good (PG) signal indicates whether VOUT is within 94.5% to 105.5% of its nominal voltage. Frequency foldback helps prevent inductor current (IL) runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. A high duty cycle and low-dropout (LDO) mode are provided for automotive cold-crank conditions.
The MPQ4326M-AEC1 is available in a QFN-14 (4mmx4mm) package, and is available in AEC-Q100 Grade 1.
