MP28163 High Efficiency Single Inductor Buck-Boost Converter with 2.9A Switches The Future of Analog IC Technology DESCRIPTION FEATURES High efficiency up to 95%. The MP28163 is a highly efficient, low Load disconnect during shutdown quiescent current Buck-Boost converter, which Input voltage range: 2V to 5.5V operates from input voltage above, below and Adjustable output voltage from 1.5V to 5V equal to the output voltage. The device 3.3V/1.3A load capability from 2.7V-to-5.5V provides power solution for products powered V by a one-cell Lithium-Ion or multi-cell alkaline IN 1.1MHz switching frequency battery applications where the output voltage is Pulse skipping mode at light load within battery voltage range. Typical 70 A Quiescent current The MP28163 uses a current mode, fixed Internal loop compensation for fast frequency PWM control for optimal stability and response transient response. The fixed 1.1MHz switching Internal soft start frequency and integrated low R N-channel DS(ON) OTP, hiccup SCP and P-channel MOSFETs minimize the solution Available in small 3x3mm QFN10 package footprint while maintaining high efficiency. To ensure the longest battery life MP28163 has APPLICATIONS an optional pulse skipping mode that reduces Battery-powered products switching frequency under light load conditions. Portable instruments For other low noise applications where variable Tablet PCs frequency power save mode may cause POS systems interference, the logic control input MODE pin GSM/GPRS forces fixed frequency PWM operation under all All MPS parts are lead-free and adhere to the RoHS directive.
