MPQ4480 Datasheet | Monolithic Power Systems

DESCRIPTION The MPQ4480 is a high-frequency, synchronous rectified, step-down, switch-mode converter. It achieves 6A output current over a wide input-supply range with excellent load and line regulation over a wide input supply range. The MPQ4480 has synchronous mode operation for higher efficiency over the output load range. Fault condition protection includes hiccup current limiting, OVP, and thermal shutdown (TSD). The MPQ4480 requires a minimal number of readily available, standard external ponents. The MPQ4480 is available in a QFN-25 (4mmx5mm) package. 6A, 36V, Step-Down Converter for Automotive, AEC-Q100 Qualified FEATURES - 4.2V to 36V Operating Input Voltage Range - 6A Output Current - Internal Auto EN Pull-Up - 20mΩ/15mΩ Low RDS(ON) Internal Buck Power MOSFETs - Integrated 4mΩ Ground Sensing Resistor - Frequency Adjustable (235k Hz to 2.2MHz) - CC Output Current Limit, 3-Level Adjustable, 2.75A/3.75A/7.5A - Forced PWM Mode - Frequency SYNC from 300k Hz to 2.1MHz - (Remend: <25% of SYNC Duty Cycle) - Spread Spectrum Option with 450k Hz f SW - EN Shutdown Discharge - Low Dropout Mode - Battery Short to Ground Protect Driver - Output Over-Voltage Protection - Adjustable Line Drop pensation - Support 1V to 20V Output Adjustable - Available in a QFN-25 (4mmx5mm) Package with Wettable Flanks - Available in AEC-Q100 Grade 1 APPLICATIONS - Automotive Infotainment System - Automotive USB Hub - Wireless Charging All MPS parts are lead-free, halogen free, and adhere to the Ro HS directive.
