LC2333
LC2333 is 3A Synchronous Step-Down Converter manufactured by LEADCHIP.
500KHz, 16V, 3A Synchronous Step-Down Converter
DESCRIPTION
The LC2333 is a fully integrated, high-efficiency 3A synchronous rectified step-down converter. The LC2333 operates at high efficiency over a wide output current load range.
This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the load.
The LC2333 requires a minimum number of readily available standard external ponents and is available in SOT23-6 package.
