Product Overview

MP2143 is a monolithic, step-down, switch mode 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. Fault condition 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. Applications include low voltage I/O system power, handheld/battery-powered systems and wireless/networking cards.
  • COT (constant-on-time) synchronous step down switcher
  • 100% duty cycle in dropout
  • Up to 3A output current, low IQ: 40µA
  • 80mohm and 40mohm internal power MOSFET switches
  • Default 1.2MHz switching frequency
  • EN and power-good for power sequencing
  • Cycle-by-cycle overcurrent protection
  • Auto discharge at power off
  • Short circuit protect with hicc-up mode
  • Stable with low-ESR output ceramic capacitors
