EVQ4323M-G-00A

EVQ4323M-G-00A 36V, 3A, Low-IQ, Synchronous Step-Down Converter in a QFN-12L Package Evaluation Board, AEC-Q100 Qualified DESCRIPTION The EVQ4323M-G-00A evaluation board is designed to demonstrate the capabilities of the MPQ4323M, a configurable-frequency (350kHz to 2.5MHz), synchronous, step-down switching regulator with integrated, internal high-side MOSFETs (HS-FETs) and low-side MOSFETs (LS-FETs). The MPQ4323M provides 3A of highly efficient output current (IOUT) with peak current control mode. The wide 3.3V to 36V input voltage (VIN) range and 42V load dump tolerance accommodates a variety of step-down applications in automotive input environments. A 1μA quiescent current (IQ) in shutdown mode allows the 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) under light-load conditions to reduce the switching and gate driver losses. An open-drain power good (PG) signal indicates whether the output 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 coldcrank conditions. The EVQ4323M-G-00A is fully assembled and tested. The MPQ4323M is available in a QFN12L (3.5mmx3.5mm) package with wettable flanks. It is available in AEC-Q100 Grade 1. PERFORMANCE SUMMARY Specifications are at TA = 25°C, unless otherwise noted.

For proper measurement equipment set-up, refer to Figure 2 on page 4 and follow the steps below: 1. Preset the power supply between 6V and 36V, then turn off the power supply. 2. Set the load current between 0A and 3A. Electronic loads represent a negative impedance to the regulator, and setting a current too high may trigger hiccup mode. 3. If longer cables are used between the source and the evaluation board (>0.5m total), place a damping capacitor at the input terminals, especially when VIN ≥ 24V. 4. Connect the power supply terminals to: a. Positive (+): VEMI b. Negative (-): GND 5. Connect the load terminals to: a. Positive (+): VOUT b. Negative (-): GND 6. After making the connections, turn on the power supply. 7. To use the enable function, apply a digital input to the EN pin. Drive EN above 1.02V to turn the regulator on; drive EN below 0.85V to turn the regulator off. If the enable function is not used, EN can be connected directly to VIN. 8. Connect a resistor between the FREQ and GND pins to set the internal switching frequency (fSW). 9. The external resistor divider sets the output voltage (VOUT) (see Figure 1). MPQ4323M R5 VOUT FB R6 Figure 1: Feedback Divider Network with Adjustable Output R5 is selected to be 100kΩ. R6 can then be calculated using Equation (1): R6= R5 VOUT 1 0.8V (1) Refer to the Application Information section in the MPQ4323M datasheet to calculate the inductance and output capacitance for different VOUT values.
