The ETA2359 is a wide input range, high-efficiency, high
frequency DC-to-DC step-down switching regulator,
capable of delivering up to 1.2A of output current. With a
fixed switching frequency of 1.4MHz, this current mode PWM
controlled converter allows the use of small external
components, such as ceramic input and output caps, as
well as small inductors, while still providing low output
ripples. Together with the tiny package ETA2359 is in,
without external compensation components, it is an ideal
solution for system designer with stringent board space
requirements. ETA2359 also employs a proprietary control
scheme that switches the device into a power save mode
during light load, thereby extending the range of high
efficiency operation.
