MP2110GQ-Z Monolithic Power Systems, IC REG BUCK ADJ 3A SYNCThe MP2110GQ-Z is a monolithic step-down switch mode converter with integrated input current limit switch. The step-down converter integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The input average current limit can be externally programmed. It is ideal for powering portable equipment that is powered by an USB port. The MP2110GQ-Z can supply 3A of load current from a 3.3V to 5.4V continuous input voltage with excellent load and line regulation. The MP2110GQ-Z input can support up to 12V transient and clamp the current limit switch output at 5.65V (Typical).The Constant-On-time (COT) control scheme provides fast transient response high light-load efficiency and easy loop stabilization. Fault condition protection includes cycle-by-cycle current limit and thermal shutdown.The MP2110GQ-Z is available in a space-saving 14-pin 3mmx3mm QFN package.Applications:• Wireless Modem Data Cards • USB Powered Devices • Cellular and Smart Phones • Portable Instrument 9icnet Electronics is an authorized Monolithic Power Systems distributor.
