The EVM3901-QW-00A evaluation board is designed to demonstrate the capabilities of the MPM3901-AEC1, an easy-to-use, fully integrated, fixed-frequency, synchronous step-down power module with built-in power MOSFETs and an inductor. It can achieve up to 1A of continuous output current (IOUT) with peak current control for excellent transient response.
The wide 4.5V to 60V input voltage (VIN) range accommodates a variety of step-down applications in 12V and 24V automotive battery input environments. The MPM3901-AEC1’s 2μA shutdown-mode quiescent current (IQ) makes it ideal for battery-powered applications.
The MPM3901-AEC1 uses advanced asynchronous modulation (AAM) mode to achieve high efficiency under light-load conditions by scaling down the frequency, which reduces switching and gate driver losses.
Standard features include built-in soft start (SS), enable (EN) control, and power good (PG) indication. A high duty cycle and low-dropout (LDO) mode are provided for automotive cold-crank conditions.
The MPM3901-AEC1 provides over-current protection (OCP) with valley current detection to avoid current runaway. It also provides short-circuit protection (SCP) with hiccup mode, input under-voltage lockout (UVLO), and auto-recovery thermal protection.
The EVM3901-QW-00A is a fully assembled and tested evaluation board. The MPM3901-AEC1 is available in a QFN-19 (4mmx6mm) package with wettable flanks, and is available in AEC-Q100 Grade 1.
