MP2164 2.5 - 5.5V, 3A, 2.3MHz, High Efficiency, Synchronous Step-Down Converter with MODE Pin in Small 2x2mm QFN Package DESCRIPTION FEATURES The MP2164 is a monolithic, step-down, switch- More than 80% Light-Load Efficiency mode converter with built-in, internal power Forced PWM and Auto PFM Option MOSFETs that can achieve 3A of continuous Wide 2.5V to 5.5V Operating Input Range output current from a 2.5V to 5.5V input voltage Output Voltage as Low as 0.6V rangewith excellent load and line regulation. 100% Duty Cycle in Dropout The output voltage can be regulated as low as 3A Output Current 0.6V. The MP2164 is ideal for powering 32m and 20m Internal Power MOSFET portable equipment that run on a single-cell 2.3MHz Frequency Lithium-ion (Li+) battery. Internal Soft Start (SS) The constant-on-time (COT) control scheme Short-Circuit Protection (SCP) with Hiccup provides fast transient response, high lightload Mode efficiency, and easy loop stabilization. Thermal Shutdown Stable with Low ESR Output Ceramic Full protection features include output over- Capacitors voltage protection (OVP), cyclebycycle current Available in a QFN-12 (2mmx2mm) limiting, and thermal shutdown. Package The MP2164 is available in a QFN-12 APPLICATIONS (2mmx2mm) package.
