EV28163-Q-00A High Efficiency Single Inductor Buck-Boost DC-DC Converter Evaluation Board The Future of Analog IC Technology DESCRIPTION FEATURES The EV28163-Q-00A Evaluation Board is High efficiency up to 95%. designed to demonstrate the capabilities of Load disconnect during shutdown MPS MP28163. Input voltage range: 2V to 5.5V adjustable output voltage from 1.5V to 5V The MP28163 is a highly efficient, low 1MHz switching frequency quiescent current Buck-Boost converter, which Pulse skipping mode at light load operates from input voltage above, below and Typical 80uA quiescent current equal to the output voltage. The device provides power solution for products powered Internal loop compensation for fast by a one-cell Lithium-Ion or multi-cell alkaline response battery applications where the output voltage is Internal soft start within battery voltage rang. OTP, hiccup SCP Available in small QFN10-3x3 package The MP28163 operates with input voltage from 2V to 5.5V to provide adjustable output voltage APPLICATIONS (1.5V to 5V), and is available in QFN10-3x3mm Battery-powered products package.
