Monolithic Power Systems (MPS) MP28162 1.5A Buck-Boost Converters

Monolithic Power Systems (MPS) MP28162 1.5A Buck-Boost Converters are suitable for operating from an input voltage (VIN) either higher, lower, or equal to the output voltage (VOUT). The Monolithic Power Systems MP28162 converters are ideal for products powered by single-cell Li-ion or multicell alkaline batteries, where VOUT falls within the battery voltage (VBATT) range. Current-mode control and fixed pulse-width modulation (PWM) frequency ensure optimal stability and transient response. The fixed 2MHz switching frequency (fREQ) and integrated low-on resistance RDS(ON) MOSFETs minimize solution size while maintaining high efficiency.

Features

  • 1.8V minimum start-up input voltage (VIN)
  • 1.2V to 5.5V operating VIN range
  • 1.5V to 5.5V output voltage (VOUT) range
  • 1.5A switching current limit
  • 2MHz fixed switching frequency (fREQ) or external synchronous fREQ
  • Selectable pulse-skip mode or Pulse-Width Modulation (PWM) mode
  • 25μA typical quiescent current (IQ)
  • Load disconnect during shutdown
  • Internal Soft Start (SS) and compensation
  • Short-Circuit Protection (SCP) with hiccup mode
  • Over-Temperature Protection (OTP)
  • Available in a small WLCSP-15 (1.3mm x 2.1mm) package

Applications

  • Optical modules
  • Portable instruments
  • Battery-powered devices
