Description

General part information

MPQ2128 Series

The MPQ2128 is a 3MHz, constant-frequency, current-mode, PWM, step-down converter. It has an integrated main switch and synchronous rectifier that make it ideal for low-voltage conversions. The MPQ2128 can supply up to 1A load current from a 2.5V-to-6V input voltage. The output voltage can go as low as 0.6V. Additional features include <1µA shutdown current, internal soft-start, cycle-by-cycle overcurrent protection, short-circuit protection, and thermal shutdown The MPQ2128 is available in a 2mm×2mm 8-pin QFN packageMeets Automotive Requirements Highly Efficient: Up to 95% 3MHz Constant-Switching Frequency 1A Available Load Current 2.5V-to-6V Input Voltage Range Output Voltage as Low as 0.6V Current-Mode Control Cycle-by-Cycle Over-Current Protection Short-Circuit Protection Thermal Shutdown <1µA Shutdown Current Internal Soft-Start QFN8 (2mm×2mm) Package AEC-Q100 Qualified
