UC3658 Overview

3A, 1MHz, HIGH EFFICIENCY

UNISONIC TECHNOLOGIES CO., LTD
UC3658
Preliminary
CMOS IC
3A, 1MHz, HIGH EFFICIENCY
DESCRIPTION
The UTC
UC3658
is a high-efficiency 1MHz synchronous
step-down DC-DC regulator IC capable of delivering up to 3A
output current. The UTC
UC3658
operates over a wide input
voltage ranging form 3~5.5V and integrate main switch and
synchronous switch with very low R
DS(ON
) to minimize the
conduction loss.
Low output voltage ripple and small external inductor and
capacitor sizes are achieved with 1MHz switching provides the
system reset function and facilitates the output sequencing design.
FEATURES
* Low R
DS(ON)
for internal switches (top/bottom) 100mΩ/70mΩ, 3A
* 3~5.5V input voltage range
* 1MHz switching frequency minimizes the external components
* Internal softstart limits the inrush current
*100% dropout operation
* Output power good indicator
* RoHS compliant and halogen free
* Compact and thermally enhanced SO8 package with exposed
paddle
