资料介绍

MP2143DJ  降压型DCDC转换芯片 3A, 5.5V, 1.2MHz


DESCRIPTION The MP2143 is a monolithic, step-down, switchmode converter with internal power MOSFETs. It can achieve up to 3A continuous output current from a 2.5V–to-5.5V input voltage with excellent load and line regulation. The output voltage can be regulated as low as 0.6V. Constant-on-time control provides fast transient response and eases loop stabilization. Faultcondition protections include cycle-by-cycle current limiting and thermal shutdown. The MP2143 is available in small TSOT23-8 package and requires only a minimal number of readily-available standard external components. The MP2143 is ideal for a wide range of applications including high-performance DSPs, FPGAs, smartphones, portable instruments, and DVD drivers. FEATURES  Wide 2.5V-to-5.5V Operating Input Range  Output Voltage as Low as 0.6V  100% Duty Cycle in Dropout  Up to 3A Output Current  Low IQ: 40µA  80mΩ and 40mΩ Internal Power MOSFET Switches  Default 1.2MHz Switching Frequency  EN and Power-Good for Power Sequencing  Cycle-by-Cycle Over-Current Protection  Auto Discharge at Power Off  Short-Circuit Protect with Hiccup Mode  Stable with Low-ESR Output Ceramic Capacitors  Available in a TSOT23-8 Package APPLICATIONS  Low Voltage I/O System Power  Handheld/Battery-powered Systems  Wireless/Networking Cards All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.
