AOZ6682CI Datasheet | Alpha & Omega Semiconductors

Description The AOZ6682CI is a high efficiency, easy to use, 2A synchronous buck regulators at fixed switching frequency for small form factor solution. AOZ6682CI works from 4.5V to 18V input voltage range, and provides up to 2A of continuous output current with an output voltage adjustable down to 0.8V. The AOZ6682CI features fixed frequency operation at heavy load and Pulse Energy Mode (PEM) at light load, providing best efficiency across whole load range. The control loop of AOZ6682CI is internally pensated, allowing for simple system design and minimal ponent count by eliminating the need of external pensation network. AOZ6682CI also features built-in enable control, internal soft-start and many protection functions, including cycleby-cycle current limit, short-circuit protection, output overvoltage protection, input under-voltage lockout and overtemperature protection. AOZ6682CI es in an ultra-thin TSOT23-6L package and is rated from -40°C to +125°C junction temperature range.
