EVQ3445-U-00A Wide-Input, Synchronous Boost Controller with Low Quiescent Bypass Mode Evaluation Board, AEC-Q100 Qualified
The EVQ3445-U-00A evaluation board is designed to demonstrate the capabilities of the MPQ3445-AEC1, a high-efficiency, current-mode, synchronous boost controller with a wide input voltage (VIN) range.
The MPQ3445-AEC1 can be used as a pre-boost controller to maintain the output voltage (VOUT) from a vehicle battery during automotive cranking or from a backup battery. The MPQ3445-AEC1 has the capability to drive 10V MOSFETs, greatly improving efficiency and minimizing power loss.
The MPQ3445-AEC1 provides either an I2C interface (default) or serial peripheral interface (SPI) to configure some key operating parameters, such as the switching frequency (fSW), current limit, light-load mode, frequency spread spectrum (FSS), dead time (DT), soft-start time (tSS), and slope compensation. fSW can be adjusted to be between 250kHz and 2.5MHz, or it can be directly synchronized to the external source.
In the event that VOUT exceeds the preset bypass threshold and VIN exceeds VOUT at the same time, the MPQ3445-AEC1 operates in low quiescent current (IQ) bypass mode. When VOUT falls below the wake threshold, the part exits bypass mode and resumes normal operation with the high-side MOSFET and low-side MOSFET (HS-FET and LS-FET, respectively) switching to regulate the output.
The MPQ3445-AEC1 also includes under-voltage lockout (UVLO), current-limit protection, and thermal shutdown protection.
The EVQ3445-U-00A is a fully assembled and tested evaluation board. The MPQ3445-AEC1 is available in a QFN-21 (5mmx5mm) package, and is available in AEC-Q100 Grade 1.
