Description
The MPQ4384-AEC1 is a configurable-frequency (200kHz to 2.5MHz), synchronous step-down switching regulator with an integrated, internal high-side MOSFET (HS-FET) and low-side MOSFET (LS-FET). It provides a highly efficient, 12A to 18A output current (IOUT) with fixed-frequency, Zero-Delay pulse-width modulation (PWM) (ZDPTM) control for an optimal transient response.
The wide 3.3V to 36V input voltage (VIN) range accommodates a variety of step-down applications in the automotive environment. A 1.5μA shutdown-mode quiescent current (IQ) allows the MPQ4384-AEC1 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) under light-load conditions to reduce switching and gate driver losses. An open-drain power good (PG) signal indicates whether the output is within 95% to 105% 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 MPQ4384-AEC1 is available in a TQFN-32 (5mmx6mm) package with wettable flanks. It is available in AEC-Q100 Grade 1.
