Description
The Future of Analog IC Technology MP28164 High-Efficiency, Single-Inductor, Buck-Boost Converter with 4.2A Switches .
The MP28164 is a high-efficiency, lowquiescent current, buck-boost converter that operates from an input voltage above, equal to, or below the output.
Features
* 1.8V Minimum Start-Up Input Voltage
* 1.2V to 5.5V Input Work Range
* 1.5V to 5V Output Range
* 4.2A Switching Current Limit
* 3.3V/2A Load Capability from a 2.5V-to-
5.5V Input Supply
* 2MHz Fixed or External Synchronous
Switching Frequency
* Selectable PSM/PWM Mode
Applications
* where pulse skipping mode may cause interference, a high-logic input on MODE/SYNC guarantees fixed-frequency PWM operation under all load conditions. The MP28164 operates with an input voltage from 1.2V to 5.5V to provide an adjustable output voltage from 1.5V to 5V. With an input from 2.5V to 5.5V,
