Gleam GL2366
The GL2366 is a step-down, current mode, DC- DC converter. The GL2366 is supported with a range of input voltages from 2.5V to 5V, allowing the use of a single Li+/Li- polymer cell, multiple Alkaline/NiMH cell, USB, and other standard power sources. The output voltage is adjustable from 0.6V to the input voltage, while the suffix part numbers GL2366- XX indicate pre-set voltage ranges of 3.3V, 1.8V, 1.5V, or 1.2V.DESCRIPTION
At heavy load, the constantfrequency PWM control performs excellent stability and transient response. To ensure the longest battery life in portable applications, the GL2366 have a power-saving PFM mode that reduces the switching frequency under light load conditions to save power. The maximum current is 600mA. All versions include internal power switch and synchronous rectifier for minimal external part count and high efficiency. During the shutdown, the input is disconnected from the output and the shutdown current is less than 0.1uA . Other key features include under-voltage lockout to prevent deep-battery discharge and Soft-start to prevent Input current overshoots at start up. The GL2366 Is available in SOT-23-5 package.FEATURES
