MP2143 3A, 5.5V, 1.2MHz, 40A I , COT Q Synchronous Step Down Switcher The Future of Analog IC Technology DESCRIPTION FEATURES The MP2143 is a monolithic, step-down, switch- Wide 2.5V-to-5.5V Operating Input Range mode converter with internal power MOSFETs. Output Voltage as Low as 0.6V It can achieve up to 3A continuous output 100% Duty Cycle in Dropout current from a 2.5Vto-5.5V input voltage with Up to 3A Output Current excellent load and line regulation. The output Low I : 40A Q voltage can be regulated as low as 0.6V. 80m and 40m Internal Power MOSFET Switches Constant-on-time control provides fast transient Default 1.2MHz Switching Frequency response and eases loop stabilization. Fault- condition protections include cycle-by-cycle EN and Power-Good for Power Sequencing current limiting and thermal shutdown. Cycle-by-Cycle Over-Current Protection Auto Discharge at Power Off The MP2143 is available in small TSOT23-8 Short-Circuit Protect with Hiccup Mode package and requires only a minimal number of Stable with Low-ESR Output Ceramic readily-available standard external components. Capacitors The MP2143 is ideal for a wide range of Available in a TSOT23-8 Package applications including high-performance DSPs, FPGAs, smartphones, portable instruments, APPLICATIONS and DVD drivers.
