EVQ4480-V-00A 6A,36V,Step-Down Converter for Automotive, AEC-Q100 Qualified Evaluation Board The Future of Analog IC Technology DESCRIPTION FEATURES The EVQ4480-V-00A Evaluation Board is 4.2V to 36V Operating Input-Voltage Range designed to demonstrate the capabilities of 6A Output Current MPS MPQ4480, which is a high-frequency, Internal Auto EN Pull-up synchronous rectified, step-down, switch-mode 20m/15m Low R Internal Buck DS(ON) converter. It achieves 6A output current over a Power MOSFETs wide input-supply range with excellent load and Integrated 4m Ground Sensing Resistor line regulation over a wide input-supply range. Frequency Adjustable (235kHz to 2.2MHz) The MPQ4480 has synchronous-mode CC Output-Current Limit, 3 level adjustable, operation for higher efficiency over the output- 2.75A/3.75A/7.5A load range. Forced PWM Mode Fault condition protection includes hiccup Support 300kHz to 2.1MHz Frequency current limiting, OVP, ground short to battery SYNC Input protection and thermal shutdown (TSD). EN Shutdown Discharge Low Dropout Mode The MPQ4480 requires a minimum number of Battery Short to Ground Protect Driver readily available, standard, external Output Over Voltage Protection components. The MPQ4480 is available in a Adjustable Line Drop Compensation QFN25 (4mmx5mm) package Available in AEC-Q100 Grade 1 ELECTRICAL SPECIFICATION APPLICATIONS Parameter Symbol Value Units Automotive Infotainment System Input Voltage VIN 12 V Automotive USB Hub Output Voltage V 5 OUT V All MPS parts are lead-free and adhere to the RoHS directive.
